Character not found

i have tried logging in 2 different characters that are in 2 different zones one has the quest for shadowlands starting and the other hasnt been logging in for over a week and both are getting character not found. Is there any way to fix this because i have been trying for almost 4 hours to log in and play and join my guildmates in leveling.

They’re working on resolving that issue:
