it says invalid session try restarting your game

hammu7 right click on the alt you want to use in the alt manager and then select new session then try to join. If this doesn’t work tell me.

hammu7 Sounds like you didn't even log in to an alt at all. You need an account to play, you know.

when i click alt manager it wont let me log onto my main account and all the alts are banned on hypixel do u know any that are unbanned thanks

ok i want a refund now wont work my account says alt failed and the free alts suck ass because they are all banned

Read this thread.

hammu7 No refunds lol, this is user error (your fault). Are you even sure your alts work? Maybe your IP got temporarily Mojang banned. None of this is the client's fault.
