There are players online the Far East server, so I don't know why some people can get on while others have problems. I just (today) paid for a static IP, and I'm going to buy a new router this weekend in hopes of getting the server to show up on the master server. If it doesn't work, I'm pretty much out of ideas. The fact that some people can log in tells me the proper ports are forwarded. It's either something with my ISP or a problem in the states. Perhaps it has something to do with the server response time to distant places. Try setting your player.ini for a higher time limit.
BTW, the static IP can take up to 7 days to coordinate, as it's a special request thing here.
