Failed to verify username

in Server Errors

mc head By Doug

Overview

You may have tried to join your Minecraft server and been rejected due to the error “Failed to verify username” or “Invalid Session”. This issue is normally because the client’s launcher failed to authenticate with Mojang’s session servers. Luckily, you can fix this error with just a few steps.

You may also be running a non-premium version of Minecraft. If you did not pay for Minecraft, you will not be allowed to join most servers due to the server running in online mode, however, it can be changed to offline mode fairly easily.

How to resolve

How to resolve on a premium server

  1. Close your game.
  2. Log off your account from your launcher.
  3. You will then be asked to type in your email and password again, please do.
  4. Once logged in, you can then start your game and join the server.

How to allow cracked players on your server

  1. Head to the Game Panel and stop the server.
  2. To the left of the panel click “Config Files” and then click “Server Settings”.
  3. Locate “Online Mode” and set it to disabled, then click save.
  4. Head back to the Game Panel dashboard and turn the server back on. It should now let you join.

Common Issues

After restarting the launcher, players still can’t join
If you are using premium Minecraft and have already followed the steps on to resolve the error and still cannot join, try restarting the server.
