[ Can not join an online server ! ]

Game mode: Multiplayer
Problem: [Crash | Bug
Region: France

Hello everyone

My problem is this: when I try to join a server in multiplayer, no matter whether it’s with or without mod, the download page appears as if I’m going to join the server, and then that put me back in the menus. Sometimes I have a message like “Lost connection with the server” and sometimes the message does not appear.
Thank you for helping me as soon as possible.

I leave you server IP or I usually play : IP :

I do not speak English …
