App not syncing but no clear error

[qu13t0ne]

Android app data failing to sync (neither push to server nor pull from server), but no errors are evident. Data has synced successfully to the phone at least once, as the articles list is populated, but at some point the sync seems to stop as no further updates are sent or received, changes on server side (thru web portal) not visible in the app & vice versa.

I do not see any error messages in the app UI, such as when swiping down to trigger sync or using the '3 dots' menu to 'Sync local changes'. I pulled the logs (attached) and do see mention of a 500 HTTP response in there, but not in the same way it is described in other issues here.

Server seems to be functioning fine when going thru the web app or using Wallabager extension from browser.

Please let me know any additional requested information as I'm not seeing an issue template. Hopefully the following is helpful:

• Wallabag android app. Installed from GitHub repo using Obtainium. Version 2.5.3
• Device: Google Pixel running GrapheneOS (Android 16)
• Self-hosted Wallabag instance. Docker compose per documentation running latest version. Behind a proxy with TLS, FQDN.
• Android app login to server instance is successful, articles have downloaded.
• In case data volume makes any difference, I have nearly 13000 articles in my Wallabag instance (recent transfer from Pocket)

Logcat and Local Changes exports are attached. I can share server logs too if someone lets me know what to look for.

Thank you!

After some further digging on the server side, I isolated the problem to a PHP memory size error and was able to resolve by increasing it in my docker compose file, allowing app sync to resume:

    environment:
      - PHP_MEMORY_LIMIT=256M

My root problem is resolved. I will leave the issue here in case the maintainers want to track the lack of error message and 'silent' sync failures as an issue. Or feel free to close the issue.
