Step 1: Enter your Steam and go to LIBRARY.

Step 2: Among the list of games, right-click Lost Ark and choose Properties.

Step 3: Go to the LOCAL FILES tab and click VERIFY INTEGRITY OF GAME FILES button.

After the process is 100% completed, restart your Steam and check if the Lost Ark Server authentication failed 10010 issue disappears.

Way 3: Disable Internet Protocol Version 6 (TCP/IPv6)

Quite a few games have IPv6 issues. Here’s how to disable IPv6.

Step 1: Open Control Panel.

Step 2: Go to Network and Internet > Network and Sharing Center. Then click on Change Adapter Settings from the left side panel.

Step 3: In the Network Connections window, right-click your current network connection and select the Properties option.

If Method 6 doens’t work for you, continue to try Method 7.

Method 6: Enable TLS 1.2

To play Lost Ark, you need to have protocol TLS (Transport Layer Security) 1.2 enabled. If TLS 1.2 is disabled on your computer, the server authentication failed error 10010 can occur. In that case, enabling TLS 1.2 can fix the error.

On Windows 7, TLS 1.2 is disabled by default. That’s why many Windows 7 users have reported the 10010 error. If you’re using Windows 7, to fix the error, you can try enabling TLS 1.2 manually.

Here’s how to enable TLS 1.2 on Windows 7:

Important: The following steps require you to modify the registry. Modifying registry incorrectly can cause serious system issues. It’s recommended you back up your registry (learn back up registry) before modifying. In case any issue occurs, you can restore the registry.

1) On your keyboard, press Win+R (the Windows logo key and the R key) at the same time to invoke the Run box.

2) Type “regedit” in the Run box and click OK. This will open the Registry Editor.

3) Go to the following:

HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > SecurityProviders > SCHANNEL > Protocols

4) Right-click on Protocols and select New > Key from the drop-down menus.

5) You’ll see a new key named “New Key #1” show up under Protocols. Rename it to “TLS 1.2”.

6) Right-click on “TLS 1.2” and select New > Key.

7) Again, rename the new key to “Client”

Right-click on “Client” and select New > DWORD (32-bit) Value. This will create a new value in the window to the right named “New Value #1”.

9) Rename the new value to “DisabledbyDefault” and press Enter. Note ensure the value is 0x00000000(0).

Then you should see the entries shown like this:

10) Close the Registry Editor and restart your computer. Then check to see if the Lost Ark error 10010 is fixed.

On Windows 10 or higher, TLS 1.2 is enabled by default. You can check if it’s disabled. If it’s disabled, you can follow the steps above (for Windows 7) to enable it.

To check if TLS 1.2 is enabled on Windows 10 or higher, follow these steps.

1) On your keyboard, press the Windows logo key.

2) Type “internet options” and select Internet Options from the result.

3) Go to the Advanced tab and check if the box next to Use TLS 1.2 is checked. If it’s checked, it means TLS 1.2 is enabled.

Ошибка в Lost Ark 10010 является следствием сбоя подключения к серверам игры и обычно происходит циклически. Однако проблема в том, что однозначно невозможно сказать, что именно стало преградой для успешного подключения: это могут быть как сбои вашего интернет-соединения, так и проблемы на стороне серверов игры, которые иной раз закрываются на обслуживание или же «ложатся» в моменты пиковой нагрузки.

В такой ситуации первое, что стоит попробовать сделать — это перезапустить игру. Попутно можно проверить в операционной системе, как работает интернет-соединение. Если с ним все в порядке, убедитесь, что запускаете игру и клиент Steam с правами администратора. Проверьте в клиенте Steam целостность файлов игры. Есть и другие методы — порой довольно экзотичные, однако их эффективность невысока: кто-то пробует отключать IPv6 на ПК в Windows, кто-то меняет настройки DNS, кто-то пытается использовать VPN, однако в большинстве случаев проблема решается сама собой с будущими входами в игру. Единого рабочего решения не существует.

How to Fix Lost Ark “Server authentication failed. 10010” Error on Windows 11

If you get the “Server authentication failed. 10010” error when logging into Lost Ark, it means one of four things: Lost Ark servers are offline; you’re not connected to the Internet; your network protocols are misconfigured; your DNS cache has been corrupted. This article will discuss this error in more detail and provide several ways to fix it.

Server authentication failed. Please try again.
[10010]

What Causes the “Server authentication failed. 10010” Error?

• When you get the “Server authentication failed” error when trying to log into your Lost Ark account, it means
• Using a VPN (Virtual Private Network). The publisher of Lost Ark, Amazon Games, has banned all connections through VPN services in an effort to combat botters. Therefore, if you use a VPN to access the Internet, you can’t log into Lost Ark. For more information about this issue, read the official post on the Lost Ark Forums.
• Damaged or corrupted Lost Ark installation files. You might get this error if some of your Lost Ark installation files were corrupted, deleted, or misplaced. You can fix your Lost Ark installation by verifying the installed files in Steam, as explained in Method 1.
• A corrupted DNS cache. If the DNS cache on your system is corrupted or outdated, the Lost Ark server may fail to authorize the connection.
• Network-related issues. You may get the “Server authentication failed. 10010” error if your Internet connection is unstable or your bandwidth is being throttled because Lost Ark requires stable and fast Internet to establish a connection with the server.

Before trying any of our fixes:

• Turn off your VPN. If you’re using a VPN and getting the “Server authentication failed. 10010” error when logging in, turn off your VPN software. If you absolutely need to use a VPN, try connecting to another VPN server.
• Check the Lost Ark server status. If you still can’t connect, visit the Lost Ark Server Status website and check if the server you want to connect to is down or full.
• Restart your PC. Restarting your PC will fix any system glitches causing the “Server authentication failed. 10010” error.
• Power-cycle your Internet router. If your Internet bandwidth is low or the connection is unstable, power cycling or resetting your router can fix any glitches your router may have. Turn off or unplug your Internet router from the power outlet, wait for 30 seconds, and then turn it back on.
• Close unnecessary third-party programs. Some programs, particularly third-party anti-virus and firewall programs, may block Lost Ark from connecting to its servers and allowing you to log in. Temporarily disable your anti-virus and firewall programs and check if that fixes the error.
• Restart Steam and Lost Ark. Restarting Steam and Lost Ark will resolve any issues that occur due to outdated cookies and cached files or interference from other software.
• Try another Steam account. Try another Steam account that was not part of the Lost Ark beta and didn’t have Lost Ark installed.
• Connect to the Internet using an Ethernet cable. Since Lost Ark requires a fast and stable Internet connection, so you may get this error if your Wi-Fi connection is weak or unstable. Therefore, we suggest connecting your PC to the Internet using an Ethernet cable. However, if a Wi-Fi connection is your only option, disconnect as many unnecessary devices from your Wi-Fi network.
