Fix Minecraft Failed to login: Invalid session (try restarting your game) Error

It is important to understand what the error message means before moving on to solutions. If the Minecraft launcher is unable to verify the authenticity of the player’s account, it displays the “Failed to login: Invalid session” error message. There are several reasons why this might happen, including the following:

• Internet connection issues
• Corrupted game files
• Invalid login credentials
• Minecraft servers down
• Conflict with third-party software

Restart Minecraft and Your Computer

It is first recommended to restart Minecraft and your computer. It is possible for the error message to arise due to a malfunction or error with the computer or game. Your computer may need to be restarted and Minecraft relaunched in order to resolve this problem.

Check the Internet Connection

There is also a possibility that an intermittent or unstable internet connection could cause the error message. Your internet connection should be strong and stable before you attempt to log in to Minecraft. To fix the problem, you can also restart your modem or router.

Delete Minecraft Session Files

Deleting the Minecraft session files may be necessary if you continue receiving the error message. There is a possibility that these files can become corrupted, causing the game to not function properly. Here are the steps for deleting the session files:

1. On your computer, launch File Explorer.
2. Enter %appdata% in the address bar.
3. Find the .minecraft folder and open it.
4. Make sure the session folder is empty, and then delete the files.

Delete the session files and then launch Minecraft again to see if the error message has been resolved.

Clear Java Cache

It is sometimes possible to resolve issues with Minecraft by clearing the Java cache, as the game runs on Java. To clear the Java cache, follow these steps:

1. Firstly, to open the Run dialog box, press Windows key + R.
2. Afterwards, in the Run dialog box, type control and press Enter.
3. Click on Java to open the Java Control Panel.

Disable Third-Party Software

Occasionally, third-party software can conflict with Minecraft, causing the game to malfunction. To determine if the error message has been resolved, disable any third-party software installed on your computer and then launch Minecraft. In addition to antivirus software and firewalls, VPNs can also be used.

Check Firewall and Antivirus Settings

When you get an error message that says, “Failed to login: Invalid session (try restarting your game),” you may have a firewall or antivirus software causing interference with Minecraft.
