I have been stuck at the loading screen with the same error for several hours:
I cannot access the game at all.
I submitted a support ticket but I am a bit worried when I see that the auto-reply contains the statement "Average waiting time - 24 hours." If I cannot access the game for 24 hours, I will lose the daily bonuses accumulated over several weeks, I could miss some personal and clan events, and eventually my shields will expire and I could lose everything.
I have a solution, you can use the App to connect to game. It's not the same that when we play with navigator, but you don't lose the day wins ;) and you can put a shield if needed.
Go there, download, install and after you can connect to game. I do it and I have the same problem than you, also sent a ticket.https://plarium.com/fr/plarium-play/
