Cannot Open Chat

[oOTriOo]

Hi, I don't know if this is the right place to post this, but anyway. Today, I cannot open chat window anymore. I cannot see any tab of chat box. There's a circle keep loading over and over again. I just don't know if this is my internet or something else. But is there anyone have the same problem as me? If yes, is there a solution for it? Thanks and sorry for my bad English.

This generally means your client couldn't connect to the game's IRC server.

 

If you open a support ticket and send them your game log they can check it out.
