First world problems - every other person having no issues joining the server apart from the lemon sat next to the bleedin' thing! Error 10054 via IGOR, local IP goes "nope, can't find you" directly in GPL. Any ideas?
Don't know the answer but I have a similar problem in that I keep getting dropped by my server. I think it is down to my LAN. Sometimes my Race PC looses internet connection and looses connection to any network drives. Don't know why this happens but I assume this is what is causing my GPL problems.
So outcome of all this is I suspect it is something to do with my PC rather than my GPL installation. Current suspect is a dodgy ethernet cable. I've got a new cat 6 cable on order
Mine was caused by the routing not recognising hairpin NAT correctly. Sorted it with some tweaking of the port forwarding rules and can now see it!
