The site gives the following error. How to deal with it?

Can you describe what you were doing when you hit this screen?

I was trying to connect to one of the cities. Then I was just thrown onto this screen. And now I can’t log out of my account, I haven’t logged in for over a week.

what happens when you click on “restart app”?

If that works can you try to clear your cache for this site by right clicking menu > Inspect > Applications > Clear Site Data

Yes, it helped. Thanks a lot
