Blood of Iron 6

I received the secret icy dungeon passes, but they do not work when I try using them on the icy dungeon entrance.
Can someone explain what I'm doing wrong?
Thanks in advance

 

I think thats the other dungeon that came with that quest line. Its over by the elephants near the quarry.

 

Thanks.
Found a dungeon at the frozen city (passes don't work there either), nothing around the quarry tho.

 

Post a SS of the passes here so I cna see them plz.

 

Not working.
The quest line states i need 1 black dragon magi interlocutor

 

that's blood of iron 1 quest, in quest dungeon tibet.

 

Thanks!
