One of those who would like to play on my server is unable to join the server. Everytime he tries to log on he gets a timed out kick. I've only seen this problem with the comcast isp so far. Is there anyway we can get this issue solved? He's able to connect to other servers both modded and vanilla just fine.
Well, maybe the ISP block some packets or something, i didn't know this ISP, so i am not sure, but.. You tried to send email to ISP?
