Thanks for the report - can you please post a screenshot from the maintenance section for both, the hub and the source? E.g. see below. I want to double check the versions and DB structure:

This should be available/fixed in the next release.
It would be great if you could test the ghcr.io/netalertx/netalertx-dev Docker image in ~15 minutes (or once the latest GitHub Action finishes).

⚠️ Please back up everything first, or ideally spin up a separate container with its own DB and config (a copy of your current setup), as database changes may occur.

After updating:

• Click the 🔄 refresh button in the blue header at the top
• Hard refresh your browser cache (shift + reload) to force js and css files reload

Disclaimer: Running the dev container long-term may lead to data loss, as upgrade paths are not guaranteed.

Thanks in advance,

Yes, on version dev-20260317-100511, I can confirm that Hub Sync works as expected.

[jokob-sk]

Thank you a lot for testing. Can you run it for a bit? I want to make sure the next release doesn't have too many bugs.

[dtech77pl]

Sure, will keep i running for a couple days, and let you know.
If you want I can also test future release to confirm it.

[dtech77pl]

With the latest update, dev-20260318-071020, everything is still working fine.

[jokob-sk]

Thanks for monitoring - really appreciate it 🙏

On dev-20260320-181016 still hub sync is working :)
