There's an issue affecting players on Xbox at the moment where logging in, queuing, or using teleporters causes a disconnect with the error message "There was an issue connecting to that instance. Please log in again. (0x002F)" Half the time I can't even log in to a given character because I get the error message. Doesn't matter if I'm trying to login to a character that last logged out in their base, or our league hall, or the watchtower, or the event instance, I'm getting that error. And on the odd chance that I do manage to log in to a hero, as soon as I get accepted into an instance I've queued for (regardless of whether it's the Vault or a raid), or whenever I try and use a teleporter to go somewhere, more often than not I'll get disconnected with the above error.
