This is def a strange one to me. I had my cleric, Aryana, got to Ethucan to upgrade her armor and she got through the doorway no problem. Upgraded her armor, did a little bit of quick shopping and then at 9:47pm CST (3 mins before the marc change), I went to take her back through the doorway, with full power and a doorway crystal. I got the message that the doorway was not active at this time and then the Crier called that the Doorway had been deactivated.
I took this at 9:53pm, I know that is when the doorway would normally be closed but just wanted to get something up there to show I tried lol
