Nextcloud auto photo upload not working?

NethServer Version: 7.5
Module: Nextcloud 14.0.3

This question probably belongs on the Nextcloud forums, but I figured I’d ask here first in case there’s something unique about the Neth integration. For the last couple of weeks, automatic photo upload from my iPhone (app version hasn’t been working. When I launch the app, I see that it has 31 files to upload, but it says “Wi-Fi network required” even though it’s connected to my home wi-fi. And even when I change the settings to not require wi-fi, it doesn’t upload the files. The app otherwise connects just fine to my server, sees the files there, can download them, etc. Thoughts on what to check?

I’d check if there’s a reported bug matching the problem:
