I need help with ban HELP

My friends banned me on the server (they are angry with me), they banned me with RPC (or something like that) and I need help to re-enter and be able to talk about it.
How do I get back?
Immediately after opening the game, the game closes.
We are creating a multiplayer game,
and i dont have social media to talk with they...
Sorry, i am french.

 

then they aren't your "friends" and you should make some new ones.

also, move on.. the internet is a big place, plenty of other ponds to swim in

but seriously, get some contact info next time

 

There isn't anything we can do... you can either wait for them to cool off and unban you or simply move on.
