Admin password not working correctly

My friend gave me the admin key for the foundry server since we co dm a game and its helpful to be able to download modules. However its extremely buggy and will often just not work when trying to leave the game. However the server owner can use it perfectly fine.


When I try to use the password here it does not work telling me that the password is invalid.
However when its on this screen the password works perfectly fine. I just don’t get it.
