Fossil Tech Online: "Failed to connect to server: The authentication are currently down for maintenance" error

[Jaythecat8]

I'm able to load up FTO (Fossil Tech Online) and attempt to connect to Ultra Dino (the server the pack comes with) and it gives me the "Failed to connect to server: The authentication are currently down for maintenance" error. Researching online, some others have this problem, but never found a fix. There is no crashing involved, so no log is available. It can't be serverside either because I see usually around 50/80 players online, and it changes every now and then.
