Fix The T.P Already (Invalid Auth.)
Sounds like something Technical Support could help you with. If you head on over there, there is a sticky to help you create a ticket. Good luck. =)
I believe that error is when you go away from keyboard for a period of time then try to use the TP, Try re-logging and it should fix it.
How could technical support help me? This is a bug within the game, i don’t control gw2’s servers and net code….
