twice in a row, this is getting quite annoying.
The pattern is:
You queue for battlegrounds
You get the ready check, you hit ready
You go to loading screen, and you remain stuck in loading screen for about 5 minutes
After about 5 minutes, you get ported back to your original location, and you get the message "cannot enter battleground" at the top right of your screen
Heck, I had a 150% scroll rolling because I level up my alts doing battlegrounds. Considering queue, loading screen, requeue, loading screen again, etc. I lost about half an hour of it.
