When managing and maintaining a website, there are a handful of HTTP status codes to be aware of. Some, such as the HTTP 499 error, can cause a timeout that interrupts your workflow. Therefore, you’ll need to ensure that your site is configured properly to avoid this issue.
Whether you’re seeing the HTTP 499 status code frequently or for the first time, it may indicate an issue with your website that needs to be addressed. The good news is that there are multiple steps you can take to resolve it.
Check Out Our Video Guide to Fixing the 499 Error
In this post, we’ll explain the HTTP 499 status code and what can cause the error. Then we’ll walk you through five potential solutions you can use to fix it. Let’s get started!
What the HTTP 499 Status Code Means
The HTTP 499 status code, also known as a “client closed request,” is a special case of the 502 Bad Gateway Error. It indicates that the client has closed the connection while the server is still processing the request.
HTTP 499 falls within the category of client-based errors. This means the issue is on the client side. Other common errors in this category include HTTP 400 Bad Request and HTTP 404 Not Found. With these errors, the problems are usually easy to define. However, HTTP 499 is more general.
The HTTP 499 error can happen on both Nginx and Apache servers. However, it is more common on Nginx servers because it was created by Nginx.
HTTP 499 is more common on Nginx because the server software handles client connections differently than Apache. With Nginx, each client connection is processed in a separate thread. Therefore, if one client connection takes a long time to process, it won’t slow down the other clients.
However, with Apache, all client connections are processed in the same thread. This can cause problems if one client connection takes a long time to process because it will slow down all other clients.
The HTTP 499 error can cause a timeout that interrupts your workflow- but with a little help from this guide, you can get right back on track 👩💻Click to Tweet
What Causes the HTTP 499 Error
Typically, the HTTP 499 error appears in Nginx logs. This can happen for several reasons, but most commonly, it’s due to either a browser timing out or a user canceling the request.
For example, a website may encounter an HTTP code 499 when it’s loaded with too much traffic. Alternatively, the error can happen when the request comes from algorithms that create issues within the site.
In some cases, this status code may also display when there is no response from the server, and the client has timed out waiting for a response. In these cases, it’s usually best to just try again later. However, if you are consistently getting this status code from a particular server, it may be worth investigating further to see if there is an overarching issue.
How To Fix the HTTP 499 Error (5 Potential Solutions)
Now that we understand more about the HTTP 499 error, let’s look at how to resolve it. Below are five potential solutions for the HTTP 499 status code!
1. Clear Your Browser Cache and Try Again
As we mentioned earlier, this error may be a temporary issue that can be resolved by simply trying to load the page again. It might be that your host or server is overloaded. Therefore, we recommend clearing your browser cache and trying again.
The process for clearing the cache will vary depending on your browser. If you’re using Google Chrome, you can navigate to the three vertical dots in the upper right-hand corner of the window, then go to More tools > Clear browsing data:
You’ll then be prompted to choose which data to clear from your browser cache:
When you’re done, reload your browser. You can also try using a different browser in the meantime. Then revisit your site to see whether the error message is still showing.
2. Disable Your Plugins and Extensions
Some users have reported that certain plugins cause the HTTP 499 status code error. Therefore, we recommend temporarily disabling your plugins to see if this resolves the issue.
You can do this by navigating to your Plugins screen in the WordPress dashboard, selecting all of them, then clicking on Deactivate > Apply from the bulk actions menu:
You can also connect to your site via a File Transfer Protocol (FTP) client or File Manager, then navigate to your plugins folder (wp_content > plugins). Right-click on the plugins folder and rename it to something such as “plugins_old.”
This will deactivate all of the plugins on your WordPress site. You can revisit your website to see whether the error message is still showing. If not, you can try activating your plugins one by one until you find the tool causing the issue.
3. Check Your Error Logs
When troubleshooting the HTTP 499 code, it’s essential to leverage your error logs. This approach will make it easier to narrow down the issue and determine whether it results from a specific plugin or tool.
If you’re not a Kinsta user, you can enable and view error logs by turning on WordPress debugging mode. However, if you’re a Kinsta user, you can quickly and easily see errors in the Log viewer from your MyKinsta dashboard:
You can also check your log files in Nginx (/var/log/nginx.error.log) and Apache (/var/log/apache2/error.log). Furthermore, Kinsta users can take advantage of our analytics tool to take a closer look at errors on your site. Then you can understand how often they’re occurring and whether the HTTP 499 error is an ongoing issue.
4. Use an Application Performance Monitoring (APM) Tool
When managing a website, it’s important to have reliable solutions for identifying and troubleshooting errors on your site. We recommend using an Application Performance Monitoring (APM) tool.
APM tools can help you narrow down which script or plugin may lead to various errors, such as HTTP 499. We include our Kinsta APM, as well as a variety of other DevKinsta tools, with all of our plans:
For example, your APM tool can help you collect valuable data and determine which applications are causing delays. Once enabled, you can use KinstaAPM to view the slowest transactions on your site, trace their timelines, and figure out the causes of issues. Our APM also provides insight into your PHP processes, MySQL queries, external HTTP requests, and more.
5. Contact Your Web Host and Request a Timeout Increase
As we’ve discussed, sometimes HTTP 499 errors can occur when a request is canceled because it’s taking too long. Some hosting providers use a ”kill script”.
In short, a kill script forces a request to be terminated after a certain amount of time. This script is often used in shared hosting environments to prevent long requests from impacting other sites.
If you’re a Kinsta user, this isn’t something you need to worry about. Each site hosted on our platform runs on an isolated software container that includes all resources and software. Everything is completely private, and none of your resources are shared, so we don’t run kill scripts.
However, when it comes to the HTTP 499 error, it’s important to note that the “client” may be a proxy, such as a Content Delivery Network (CDN) or load balancer. A load balancing service can act as a client to the Nginx server and proxy data between your server and users. This can cause a timeout that cancels the request to the Nginx server.
PHP timeouts happen if a process runs longer than the maximum execution time (max_execution_time) or max_input_time specified in your server’s PHP configuration. You may encounter timeouts if you have a busy website or scripts that need longer execution times. Therefore, it might be necessary to extend your timeout value.
Let’s say you have a request that is expected to take 20 seconds to complete. If you have an application with a timeout value of 10 seconds, the application will probably time out before completing the request. You’ll likely see the HTTP 499 status code in such an instance.
Therefore, it’s wise to check with your host about the values set on your server. At Kinsta, the default max_execution_time and max_input_time values are set to 300 seconds (5 minutes). The maximum PHP timeout values vary depending on your plan.
If necessary, you can reach out to your hosting provider to request a timeout increase. As a Kinsta user, you can open a ticket with our support team.
With help from this guide, you can ensure your site is properly configured to avoid seeing this error in the future. ✅ Here’s how… 🚀Click to Tweet

A non-standard status code introduced by nginx for the case when a client closes the connection while nginx is processing the request.
The HTTP 499 status code is not a standard HTTP status code, meaning it is not defined in the HTTP/1.1 specification. This status code is used by the nginx web server to indicate that the client closed the connection before the server could send a response.
The HTTP 499 error typically occurs when a client terminates the connection before the server is able to respond, such as when a user cancels a request or navigates away from a page before it fully loads. In some cases, the error may be caused by a misconfigured server or network issue that disrupts the connection between the client and server.
499 status code example
A 499 status code is not an officially recognized HTTP status code, but it is sometimes used by servers to indicate that a client has closed the connection without receiving a response. Here’s an example of a request and response:
Request
GET /index.html HTTP/1.1
Host: example.com
Response
HTTP/1.1 499 Client Closed Request
Server: nginx/1.19.6
Root causes of a 499 Status Code
The HTTP 499 error is specific to the nginx web server, and it occurs when the client closes the connection before the server can send a response. There are a number of reasons why this could happen, including:
Network issues:
If there is a problem with the network connection between the client and server, such as a dropped connection or high latency, the connection may be lost before the server can respond.
Client-side issues:
If the client navigates away from the page before it fully loads, or cancels the request before the server can respond, the connection may be terminated before a response is received.
Server-side issues:
If the server is experiencing issues, such as a high load or a misconfiguration, it may be unable to respond to the client’s request in a timely manner.
Firewall or security software:
If there is a firewall or security software in place that is blocking the connection or interfering with the communication between the client and server, the connection may be lost.
Misconfigured server:
If the server is misconfigured, it may not be able to properly handle requests and may result in a 499 error.
Server-side timeout:
The server may have a configuration that sets a timeout period for the response, and if it exceeds the limit, it may close the connection and result in a 499 error.
These are just a few examples of what could cause an HTTP 499 error. In order to determine the specific cause of the error, it may be necessary to investigate further using server logs or other troubleshooting methods.
Troubleshooting a 499 Status Code
Since the HTTP 499 error is not a standard HTTP status code, it can be tricky to troubleshoot. However, there are a few general steps that you can take to try to identify and resolve the issue:
- Check the server logs
If you have access to the server logs, check to see if there are any entries that correspond to the time that the HTTP 499 error occurred. This may provide clues as to what caused the error.
- Check the network connection
Verify that the network connection between the client and server is stable and reliable. Check for any network issues, such as dropped packets or high latency, which could cause the connection to be lost.
- Check the browser cache
Clear the browser cache and cookies to ensure that the error is not caused by a cached resource or cookie.
- Disable browser extensions
Disable any browser extensions that could be interfering with the connection, such as ad blockers or security software.
- Try a different browser or device
If the error persists, try accessing the site from a different browser or device to see if the issue is specific to the current configuration.
Does a 499 status code affect SEO?
Since a 499 status code is not an officially recognized HTTP status code and is not a common error, it is unlikely to have any direct impact on SEO. However, if it is a persistent issue on your website, it could affect user experience and lead to lower engagement and higher bounce rates, which could indirectly impact your SEO.
Return to List of HTTP Status Codes
Whether you’re browsing the internet as a user or maintaining and managing a website as a web admin, you’ll encounter certain common errors or HTTP error codes on a daily basis. Some error codes, such as HTTP 499, can cause downtime that can affect businesses of all sizes.
After all, websites are one of the primary ways customers access and interact with products or services.
When a user tries to access a website, but it’s not available due to any reason, they often receive an error message generally represented as an HTTP status code that indicates the type of error.
Like HTTP status codes 100-500, there is plenty of HTTP error codes out there, ranging from 100 to 500. However, for now, we’ll focus on the most frustrating, dreadful, and common HTTP error code – the 499 error.
In this blog, we’ll be explaining what HTTP error 499 actually means, its causes, tips to prevent it, and the best working methods to fix it. Let’s get started!
What is HTTP 499 Status Code Error?
The HTTP 499 error status code is a unique and special case of the 502 Bad Gateway error that is caused by the client side. The 499 error indicates that a client closed the connection before the server could send a response, and the server is still processing the request.
Error 499 is unique because it doesn’t occur from the server end, unlike most errors where the server is often the main culprit due to misconfiguration or some software bug.
But in this particular type of error, the main culprit is the client (web browser or a user agent) that closed the connection before the server could send a response. This means the server was doing its job correctly – processing the request – but the client didn’t wait for the response to be sent back.
This error has not been listed or a part of the official HTTP/1.1 standard, hence it is not well recognized by all web servers.
Similarly, we have two more common errors that fall into the same category: HTTP 404 Not Found error and HTTP 400 Bad Request error, which you must also check out.
Why does the HTTP 499 Status code Occur?
Http 499 status code is specific to only Nginx web servers only and there can be multiple reasons why it can happen. But some of the most common are:
- Network Issues: Network problems can cause lost connections between client and server due to issues like dropped connections or high latency.
- Server-side issue: Server issues like high load or misconfiguration can cause delayed response or failure to respond to client requests.
- Client Side issue: Termination of connection before response due to canceled request or navigating away from the page during loading of the page by the client.
- Firewalls and Anti-virus software: Firewall or Anti-virus software interference can lead to lost connections or blocking of communication between client and server.
- Misconfigured Server: If the server is not properly configured, it won’t be able to handle incoming requests from clients correctly, which may result in Error 499.
To better understand what is triggering error 499, you need to have a basic understanding of how modern web applications work.
In a general web application, a client or your browser sends a request to a web server. Then the web server processes the request and sends a response back to the client.
During the entire communication process between the client and the web server, there are usually security devices installed, such as firewalls or load balancers. These devices play an important role in distributing traffic across multiple servers and filtering out malicious requests.
However, sometimes these devices can be misconfigured and can cause 499 errors to occur. Another common cause for triggering 499 errors is on the client side.
For example, a user may close the browser or switch to another page before the server sends back the response to the browser.
Alternatively, any installed extensions or proxy servers used may also interfere with the communication between the client and the server, causing the 499 error.
These are some of the general and common reasons that might trigger Error 499. However, to determine the exact cause of the error, further investigation is needed, along with trying different troubleshooting methods discussed below.
Now that you understand the meaning of the HTTP 499 status code and some of the main reasons that cause it, let’s check out the top 5 methods that can help you fix it.
1. Purge your browser cache and Reload again
As we mentioned earlier, the HTTP 499 error is not a permanent issue and can sometimes be easily fixed by simply reloading or refreshing the web browser. It is also possible that your server or host may be overburdened with multiple requests, so you should clear your browser cache and try browsing the site again.
Note: Since Chrome has a major Browser market share, here we will be using Chrome for this tutorial.
Step 1: Depending on your browser, navigate to the settings menu. In Google Chrome, you can click on the three vertical dots in the upper right corner of the window.
Step 2: Select “More tools” and Click on “Clear browsing data“.
Step 3: A pop-up window will open on which, you can select all three options under the “Basic” section or just select the “Cached images and files” as shown in the picture below.
Step 4: Click on “Clear data” to initiate the process.
2. Check on a Different Browser or Device
If the error still appears, you can try accessing the website on a different browser or even on a different device to see if the error is specific to the device or configuration.
3. Temporarily disable Plugins or Extensions
Some reports have shown that faulty plugins and extensions can also cause the HTTP status499 error. Therefore, you should check whether a faulty plugin is the main culprit or not.
To do this, Go to your WordPress Dashboard > Plugins and select all the plugins, and then click on Deactivate > Apply from the bulk action menu.
In case you are unable to log in to your WordPress dashboard for any reason, you can alternatively connect to your site via FTP or a file transfer protocol client such as FileZilla. Go to the wp_content folder > plugins and right-click on the plugin folder you want to edit and rename it to anything you like.
This method will help you deactivate all the installed plugins on your WordPress site. You can then check for the faulty plugins by activating them one by one and trying to access the site simultaneously to see if the error message still appears. Repeat the process until you find the faulty plugin.
4. Check Error Logs
If you have access to the Error logs, look out for the suspicious entries that correspond to the time that the HTTP 499 status error code appears.

5. Disable Firewall or Antivirus Software
Certain firewalls or antivirus software may interfere with communication between the client and the server, resulting in 499 errors. Try disabling your firewall or antivirus software temporarily to see if it resolves the issue.
Therefore, you can try temporarily disabling them and check whether it fixes the issue or not.
For Windows users:
Step 1: First, you need to open your computer’s control panel. To do this, click on the “start” menu on your desktop and type in “control” in the search field.
Step 2: Next, select “System and Security” from the control panel options. This will take you to a new page.
Step 3: On the new page, you’ll see an option for “Windows Defender Firewall.” Click on “Allow an app or feature through Windows Firewall.”
Step 4: In the next window, you’ll see a list of apps and features that are allowed to communicate through your firewall. To change these settings, click on “Change settings.”
Step 5: If you don’t see your DNS client on the list, you can add it by clicking on the plus (+) icon.
Step 6: To temporarily disable your firewall, uncheck the box next to “Windows Defender Firewall” and click on “OK” to save your changes.
Step 7: Alternatively, you can adjust your firewall settings by finding the DNS client or any other application you want to configure and checking or unchecking the boxes next to the desired settings.
Step 8: Once you’re done adjusting your settings, click on “OK” to save your changes.
Note: It’s important to only disable your firewall temporarily if you need to troubleshoot a connectivity issue. Leaving your computer without a firewall can expose it to potential security threats.
6. Contact Your Web Host
If none of the above methods can fix Error 499, the final option is to contact your web host. Sometimes, the request may be canceled due to taking too long to process, causing Error 499. To prevent server overload, web hosts generally use a kill script to forcibly terminate such requests.
The server may be configured to have a response timeout period, and exceeding the set limit may result in a connection being closed and a 499 error occurs. For instance, suppose you have a request that is expected to take 15 seconds to complete, but the server timeout value is set to 10 seconds. This will result in a timeout before completing the request.
Therefore, it is highly recommended to check with your web host about the timeout values set on the server, and if possible, request an extension of the timeout value.
If you are a WPOven user, you don’t need to worry about this issue. Each site is hosted on a Virtual Private Server, and all resources are allocated dedicatedly.
Conclusion
In this blog, we have discussed the 499 error, a frustrating and common error that can cause downtime for websites. We have explained how this error is caused by the client, such as a web browser, closing the connection before the server can send a response.

Frequently Asked Questions
What is Cloudflare 499 error?
The 499 error code is a specific code used by Nginx, indicating that the client has closed the connection while the server is still processing the request.
What is Nginx 499 error code?
The Nginx 499 error code is an HTTP status code exclusive to Nginx web servers, which means the client has closed the connection while the server is still processing the request. Hence it is considered a client-side error.
What is AWS load balancer 499 error?
If the server is unable to respond to the request within the load balancer’s timeout limit, the connection will be terminated, resulting in an error 499 being displayed.
HTTP response status code 499 is an unofficial client error that is specific to both ArcGIS with 499 Token Required and nginx with 499 Client Closed Request.
Usage specific to ArcGIS
When the 499 Token Required status code is received, the server is expecting a token to accompany the HTTP request but it was not submitted. To solve this error, the HTTP request needs to be resubmitted with a valid token.
Usage specific to nginx
When the 499 Client Closed Request status code is generated, it means that the client has closed the HTTP Connection in advance of the server completing the task. As such, the final response cannot be sent and this status code is only available in the nginx logs.
Note
Search engines like Google will not index a URL with 499 response status, and consequently, URLs that have been indexed in the past but are now returning this HTTP status code will be removed from the search results.
Takeaway
The 499 Token Required / Client Closed Request status code is specific to ArcGIS, where the HTTP request required a token that was not included, and nginx, where the client closed the HTTP request prematurely.
