Battle.net app is stuck at “Loading account information” Linux

I was fixing another bug at baatle.net now it is done after a few days but this got at the foreground now -.- . So I start the battle.net application I enter my details and then the games tab stays on "Loading account information" for a very long time. Options are working nice, the other tab with the news is working smooth also, but this does not.. At the end of this 1-hour waiting I get a message which says:

"Oops, something crashed *blah blah blah*"

And redirect me to a blizzard help page. The summary was a problem with communicating the update manager/agent.

Also I am running it on Linux via PlayOnLinux.

What I have tried:

1. Closing battle.net app and starting it again.
2. Restarting the whole system and running it.
3. Launching it with Wine directly (gives me another error there – Can not reach the update manager at all).
4. Creating a shortcut and launching it from there.

If someone has any ideas it would be great.

Thank to everyone who loss their time here! {:

Edit:
I waited it to the end now and this is the actual message:

Oops! An error occurred while loading game information:
Whoops! Looks like something broke (or crashed). Please try restarting
the Battle.net desktop app and/or your computer. More help: 'Here they give link to this - https://us.battle.net/support/en/article/cannot-communicate-with-battlenet-update-agent'
