Hello, I recently upgraded to 0.6.5 after not playing for a month or so. My friends and I played for months on my server running 0.6.1, but now they are unable to connect to my server. I don't know what happened and I've tried everything. The proper port is open, and I just launch the server and it used to work, now it doesn't!
Any ideas? I've tried resetting router, opening other ports, etc. Nothing seems to work.
