How To Fix “Failed To Login Invalid Session Try Restarting Your Game” On Minecraft

Are you getting “Failed to connect to the server Failed to Login Invalid session” error in Minecraft?

As Minecraft enthusiasts, you know how exciting it can be to jump into a multiplayer server or LAN world and engage with fellow players.

However, at times, technical issues can hinder your gaming experience, leaving frustrated and unable to connect.

One such common error is the “Failed to connect to the server, Failed to Login : Invalid session (Try restarting your game)” or “Failed to connect to the server, Failed to Login : Invalid session (Try restarting your game and the launcher)“

In this guide, I will discuss what causes this error message and how to fix it.

What Causes “Failed To Login Invalid Session Try Restarting Your Game” Error On Minecraft

The “Failed to Login: Invalid Session” error in Minecraft typically occurs due to an invalid session ID.

This issue arises when you log into your account, launch a new instance of Minecraft without closing the old one, and then attempt to log in again.

As a result, the old session ID is invalidated when the new connection is established, and the server will only recognize the new session ID.

Consequently, when you try to join a server, this error message will be displayed.

Another possible cause for the “Failed to Login: Invalid Session” error in Minecraft is using a cracked version of the game, such as TLauncher.

Cracked versions might not have the proper authentication and session management systems in place, leading to errors when trying to connect to servers or join LAN worlds.

How To Fix “Failed To Login Invalid Session Try Restarting Your Game” On Minecraft

Step 1: Restart Your Game And Launcher

The most common solution to the “Failed to Login: Invalid Session” error is to restart your Minecraft client and launcher. Follow these steps:

1. Close the Minecraft game.
2. Exit the Minecraft launcher.
3. Reopen the Minecraft launcher.
4. Launch the game and attempt to join the server or LAN world.

If the error persists, proceed to the next step.

Step 2: Verify Your Internet Connection

Ensure that you have a stable internet connection to avoid session disruptions.

If you’re experiencing connectivity issues, try resetting your modem/router by unplugging it, waiting 30 seconds, and plugging it back in or connecting via a wired connection.

Step 3: Disable Firewall Or VPN

Firewalls and VPNs can interfere with your connection to Minecraft servers. Temporarily disable any firewall or VPN software, and attempt to join the server again.

• To disable a firewall, navigate to your computer’s security settings, find the firewall settings, and turn it off temporarily.
• To disable a VPN, access the VPN client, and disconnect or exit the software.

Note: Don’t forget to re-enable your firewall and VPN after troubleshooting to maintain your online security.

Resolving The Issue For Server Owners

If you are a server owner experiencing “Failed to Login: Invalid Session” error, follow these steps to resolve the problem:

1. Access your server’s files and locate the server.properties file.
2. Open the server.properties file and find the online-mode setting.
3. Change the online-mode setting to false.
4. Save the file and restart your server.

This change will allow players to connect without session ID validation.

Fixing The Error For Cracked Players (TLauncher)

For players using cracked versions of Minecraft (e.g., TLauncher), follow these steps:

1. In TLauncher, navigate to the “Accounts” menu item and log in using your Minecraft/Mojang credentials.
2. Join a server that allows cracked versions or does not check for licenses.
