After all, sorry for my bad English.
So, the problem is, when I try to connect to my server, I see the list of realms, but impossible to connect to my realm. It say that my server is offline.
My server is hosted on a windows dedicated server. All ports are opened and the firewall is turned off.
My server run with world of Warcraft 5.4.8
Thanks for helping, and, sorry for my bad English, I’m French.
