Why cant i do layer 2 of The Upper Reaches in Torghast?

I am trying to do Upper Reaches in Torghast but it won’t let me pass layer 1. I have 100% layer 1 but layer 2 wont open. Just says I don’t meet the requirements. Does anyone know why?

The Twisted corridors and the ones adjacent you cant skip levels for you have to do each one completely. You may have started on one with a group once but you didnt finish or you arent in the group anymore. So you have to redo solo.

Just redo it again? Uhh I’ve been running torgast daily for weeks. (not the last two days though), but . . . I think you should just be able to do it or redo it on level 1 and see if it works - also check wow head.
