Legion Raid bug?

I’ve only done one raid this week, and did not clear Gate 2
But when I tried looking to clear it today, I got a message that my entry count is exceeded…

I don’t have any alts I can use for Legion Raids, and only tried the legion raid once this week. So I don’t understand why it says entry count exceeded.

(Could it possibly be because I lost connection while doing gate 2 with my guild? They cleared it but I disconnected so I could not get rewards and so did not clear it?)

Just curious ^^
