I tried to queue up for a SoO 25N at Malkorok this evening. My lock has the same lockout (8/14N) for this week. I met the item level requirements. However, when I tried to wait list, all I got was "not qualified", but no specific reason. Usually I'll get a specific reason, like item level too low, invalid role, invalid class, but I don't here.

There were two of them listed at the time. One I managed to wait list for, the other which I highlighted gave me the error. Later on I tried waitlisting for the one I was successful with before, and I got that error as well. Any idea what could be causing this?
