iOS app background sync fails

[sidamos]

The bug

I get a notification on my iPhone that Immich background sync starts. Shortly after, I get another notification that background sync failed.
However, there are no new photos to sync since last time I synced manually.
When I then start the app, the manual backup start button is disabled, of course, because there are no new photos.
For the time when I got the 2 notifications (12:18), there is nothing in the app log.
I started the app at 12:20.

More info:
I am using a subdomain via internet, SSL certificate is for the main domain, SSL verification in the app is therefore set to off.
Also, I am using Apache reverse proxy with basic auth. So, I have basic auth user and password in the URL.
Since the app is otherwise (besides the described error) working fine, I would expect that my setup is supported.

I am not very familiar with Apache proxy, does it have any setting to limit the body size to have a certain size?
