"server not responding" on downloading mods
I have some information that may be helpful pertaining to this problem.
It seems there is some sort of timer that is activated when you join a server, and it is being run when you join a server and not stopped when the client begins downloading mods.
You can see by the image above that the connection dialogue is actually going on behind the mod download dialogue.
Of course, just as i would expect after 60 or so seconds of not connecting (client is busy downloading mods) the client exits both dialogues and gives the error below:
This happens on any server i try to join that takes me longer than the timeout period mentioned above. The timeout time also seems to change, so perhaps its not necessarily a timer. Sometimes its consistent and sometimes its not. Perhaps ping related, not sure.
