503 - Can't see passwords


I can no longer access my passwords. When I open the passwords app over the browser I have to enter my master password as usual. But after that there is just the spinning load-icon and I get a popup with an 503 error.

I also tried the Firefox extension and the android app, both are not working, as well.
I tried entering a wrong master password on purpose and got a wrong password notification.

It was working a few days ago and I did not change anything by myself. I did notice, that the passwords app got updated to 2023.9.30 by autoupdate.

How can I get the app working again? Thanky for the help.
