templeofsleepers

I have the purple medallions but still can not pass the barriers into the Temple of Sleepers in the Gorge of the Kings. What am I missing?

In temple of sleepers quest I cleared teleportation maze and then entered Azeran chamber but he was not there and my journal description changed to Met and confronted Azeran in deepest of temple! Now barrier is still on and that sacrcophagus also not opening! Stuck there😮 I had already talked...
