Not sure what caused this.

Went to play this morning and I can't log in because there is this big, white square where the Lon in area is. When I move my cursor over it, I get the busy circle next to my icon.

I've closed out other programs, rebooted my pc. First time I've ever run into this.

Any suggestions?

PS: After about 5 minutes, I just received an error of 503: HTTPS System Error.
