It is GTXGaming and hosted in Dallas. I tried to find central location for it. The server is on the most current build, as well. I am not really sure what the invalid flag means for servers.
I can try to disable the password for a bit later if people want to try it and see if it works that way. Also, I have 30 slots available on the server, so if we don't get a large population, it might be beneficial to either open it up, or find another community to join to make it more lively.
