I know this sucks, but sad fact is that TW has blocked NA players from their servers. Currently working on a way around this and hoping this IP block gets overturned like the KR server.

My theory is that OGP's NA Server had a hand in this. They couldn't compete with TW and they decided to just eliminate the competition. Regardless of why this happened, it still sucks. I'd rather quit SDGO than join NA's piece of crap server.
