Locked out on Heroic Dungeon with all bosses available

I queued for specific dungeons on the Dungeon Finder, quit right at the start (no mobs, nothing), got the 30 min lockdown, which is fair enough.

But the dungeon also appears now locked and I cannot queue for it anymore. Even though all bosses show as available.

I presume you get locked into a HC instance if maybe some other player has advanced further and engaged some mobs even in another part of the dungeon?

nope. you get locked the moment you enter no matter what, don’t ask me why :man_shrugging:

Was it End Time? You’re locked the moment someone enters the portal and reveals the first echo. Otherwise, people would be quitting the moment they see it’s Ruby Dragonshire and re-queue hoping for an easier one.
