Additional Info:
There were some packages upgraded to php8.3. After this the problem started.
I removed this packages and also some meta packages without version (php …)
Now I don’t get error messages, just an empty page. Completely white.

From the looks of it you’re using PHP-FPM and Nginx.

  • Check your Nginx error log
  • Confirm the fpm service is running.

Also since you’re changing PHP versions, you’ll need to port your PHP configuration, etc.

There is nothing in error.log from nginx, what relates to nextcloud.

php8.2-fpm

These log entries are all cut off. Can you post the raw entries?

Oh yes, sorry.

It’s working again.

I just installed php8.2-soap and php8.2-xml. After this my nextcloud instance is working again.

Thank you for all answers.
