Greetings. Today the app is not working again. It produces Error code: 504-backend. For some reason this happens about once a month :(

What do you see in your web app logs?

i am facing the same issue

On September 5th, many people had the same problem. Then they said on the forum that a problem arose during technical work and soon everything was fixed, the problem was with the host. I'm sure everything is fine with the application, it worked perfectly for several months.

It looks like we found the problem and it should work now. Sorry for that.

Thank you, it worked

Great, thanks for confirming!
