Error: Failed to join any instances

was running a breachstone with a rarity deadeye until boss, put portal then went to character selection screen to choose amazon to kill the boss. When i try to log back deadeye i get Error: failed to join instance. he got stuck inside the twisted domain that i finished. To clarify i ran a map with amazon after i finished the breachstone.
Stuck Deadeye name: MobiusAnger

got resloved on its own
Just after posting i tried to login once more after being stuck for 30 mins and it worked, i am able to log back in.
sorry i thought i would lose the character forever
Ty!
