Burial chambers map keeps logging me out.

As written. You enter the map. It's ok for a minute or so. Then server error. Portals are not here. No loot from the map.
I. Have already. Burned through 10 or so T14 maps on it. Not completed. Not tried. Burned. No other words comes to mind.
What is going on with it? Anyone else has that issue, or just me?
