What is this happening?

since I switched to the NA server this happened to me, and I did not care much, but a couple of days ago I was out of the light when I was leaving (they gave me a low priority queue) and I must wait 10 minutes to be able to enter starting, the problem is that when I go at 2:50, he puts that message to me and I have to start the 10 minutes again

Game on a Mac OS High Sierra version 10.13.6

If anyone knows why this happens and knows how to solve it, I will appreciate it a lot.

Excuse me for my English, I still practice it: D
