Bitrix ошибка ip адрес клиента изменился продолжение невозможно

Перейти к содержимому

There are two possibilities why you would receive the error message “IP address has changed” from cPanel.

1) Your Internet Service Provider (ISP) has a short DHCP lease time, causing your IP address to be renewed/released and reassigned while you are logged into cPanel.

2) You are attempting to login into cPanel using the same account from two different devices concurrently.

There are two ways to resolve the error message.

The first method is to login into cPanel again, which usually resolves the issue.

However, if this method doesn’t work, you may attempt method #2, which is to configure your cookie IP validation settings. Method #2 is only applicable for accounts with cPanel and WHM version 11.28 and above.

Note: You must have a Cloud Hosting Reseller Account or higher.

Step 1 – Login into cPanel and WHM.

Step 2 – Click on “Main” -> “Server Configuration” -> “Tweak Settings” -> “Security Tab”.

Step 3 – Look for “Cookie IP Validation”. For more information, you may click on the “?” sign. It reads: Validate the IP addresses used in all cookie-based logins. This will limit the ability of attackers who capture cPanel session cookies to use them in an exploit of the cPanel or WebHost Manager interfaces. For this setting to have maximum effectiveness, proxy domains should also be disabled.

Step 4 – Change the settings to “Loose” and the frequency of re-authentication will be lowered. You can also disable it entirely.

Step 5 – Disable proxy domains. If you do not perform this step, you have to utilize a proxy server with a static IP address to establish and maintain your connection.

Step 6 – Clear your web browser’s cache and login into cPanel like normal.

“Your IP has changed” cPanel error – When do you see this?

There are 3 situations in which this problem occurs.

• Your internet service provider (ISP) provides a dynamic IP address or they use short DHCP lifetimes.
• When you try to login to the same cPanel account via 2 different devices with 2 different IPs.
• You use a proxy or VPN that changes the IP every few minutes.

What causes “Your IP has changed” cPanel error?

This setting validates IP addresses for cookie-based logins. This denies attackers the ability to capture cPanel session cookies in order to gain access to your cPanel & WHM interfaces.

In order to provide you with maximum security, on our platform, Cookie IP validation is set to strict — The system requires that the access IP address and the cookie IP address match exactly.

Otherwise, it will log you out automatically and you will see the error “Your IP has changed. Please login again“.

How to fix “Your IP has changed” cPanel error?

Usually, re-login to cPanel will succeed. But, to fix this permanently, you must ensure that the IP Address remains static.

In order to fix this permanently, please explore the below options:

1) Use a static IP Address

As we discussed, some ISPs constantly change IP addresses. As a result, users must enter the credentials every time to access cPanel.

2) Access cPanel via a static link

Unfortunately, not all ISPs provide static IPs.

In such cases, we suggest you access your cPanel using a static link that contains the server name and the cPanel port.

For instance, website owners can use the static link  ‘https://server_name:2083/’ to access cPanel.

Here, server_name is the server name and 2083 is the cPanel port.

3) Use the Free VPN in Opera web browser

You can take advantage of Opera’s free VPN which will provide you with a static IP that doesn’t change frequently. Their free, built-in VPN requires no subscription, payment, or additional extensions.

The first step is to download Opera and to install it.

To activate the free VPN for the first time, enable it in Menu -> Settings -> Privacy -> VPN. From now on you will see an icon on the address bar showing VPN status. Simply click on it to trigger VPN service on and off. You can then select your desired virtual location and also see stats on the data used.
