Some guy said do /qu so i did it quit my game i started the game again and tried to join the server agian and it said not connected what do i do

Try reconnecting to your source of connection (router or whatever)

/qu means quit. It just makes you close the game, some people try to troll you by saying you should type that.
It has nothing to do with you not being able to join the servers, the server was probably just full of something, and there's quite the chance that it's fixed already.

I cant connect to any servers and i have restarted my game 6 times it isnt fixed for me

tried that @FleshMon didn't work

Thank you both for helping. I fixed it

Allright, closing.
