An issue with getting into an LFR group for Pinnacle of Storms.

A couple days ago now I entered a queue in LFR for Pinnacle of Storms which is the last part of the Thunder King raid and when I get to the loading screen I just get stuck there until it disconnects me. I tried like 5 more times after that happened and still nothing happened, just stuck on the loading screen. After a while though when I log back on that character I'll be back at my inn. I tried entering again to see if it was just some random bug but when I did, it happened again. Does anyone else have this problem or at least have a similar problem to this? I can enter other LFR raids no problem just like last night I was doing the new Siege of Orgrimmar raids and entered in fine. It's just that one segment of the Thunder King raid that I can enter on LFR.

I didn't find the right solution from the Internet.
