I apologize if the answer to my question is on the site but I have been looking for too long.
Let me explain, twice this week (it's the case now) I got stuck on "connecting" when accessing the list of my characters. Finally, I constantly get the message "unable to connect" while I'm not banned, my connection is working and my roommate is playing on Frostmourne right now.

What should I do?
Have a great day and a big thank to devs for the massive work!
