I have the same problem, except that i was never able to play.
But i have a fix, at least for my problem.
I'm from germany using a hybrid technology for internet which includes LTE. If LTE and cable both are activated i'm not able to play. But if i disable LTE and only using cable for internet i have no problems.
But i'm not willing to disable LTE everytime i want to play on Elysium. There is an option to choose ports with which i only use normal cable but to use that i need to know the ports Elysium is using.
Maybe some of you can help me with that.
I had the same problem with normal WoW but Blizzard has a posting where you can find any ports they are using. After deactivating lte for these ports i was able to play WoW on official realms.
