While playing Minecraft, I changed my name and now I can't access any servers. I've tried logging out and back on, but it still won't work. I'm afraid that I may not be able to play Minecraft anymore...

    Did you actually log out? As in, did you open the launcher and click "log out"?

  • Are these servers whitelisted? That would be a simple exclamation!

You most likely just need to go in to the console and type /whitelist add {new name}

  1. The Session ID that your client is using, might be out of date.

Try logging out & in in the Minecraft Launcher.

If that does not work, you might want to go to your .minecraft folder (located at %appdata% on Windows, and in your /home/ directory on Linux) and delete the file called 'launcher_profiles.json'. After this, go to your launcher and log in.

  1. You are playing in an old version (specifically in a lower one than 1.7.6, not including 1.7.6) or with mods.

  2. You have been banned from the servers, or if they are whitelisted, you are not whitelisted anymore.

You must log in to answer this question.
