Help please something important

ok today the game asked me to update and i updated its on OPT out

and then i try to join facepunch ireland and i can’t why

it tell me

disconnected:wrong connection protocol: server update required!

why the server didn’t update yet!?

Either the server hasn’t been updated, OR the server’s been switched to a development build that’s ahead of the standard client.

Either way, this happens to different servers every update.

and when i could be online to play on the server again please?
