Nextcloud integration fails

Third party integrations
1

So, I used the Nextcloud integration to get some indicators going and it worked fine for all my HA instances. However, I think after upgrading to HA 2026.9, it stopped connecting. Here’s what I tested:

  • All instances of HA integration have stopped.
  • I did not upgrade Nextcloud (33.0.8)
  • I did upgrade HA (2026.9, then 2026.9.1)
  • Nextcloud seems to be working fine and all other integrations work (e.g. calendar)
  • Refreshing the integration didn’t help
  • Removing and re-adding didn’t help
  • Upon checking the NC side, it appears to reset the “last use” of the app password to “a few seconds ago” every time the integration reloads. So I think NC thinks everything is fine (not an auth error)

HA logs issue this as an error:

asyncio.exceptions.CancelledError: Global task timeout: Bootstrap stage 2 timeout

It also issues several warnings with “Waiting for integrations to complete setup: {(‘nextcloud’, ‘[long key]’): [number].[number]}” but I suspect that’s just it waiting for the integration to start.

I even went to another HA and started fresh and it would behave the same (stall, than fail).

Anyone else using the integration? Does it work for you? Am I looking at the wrong logs? It just looks like it says “timeout” to me.

I have same/similar situation after last update.

Head here and click on known issues.
If there is one for this, it should guide you what to do. If not then add one…

Thank for the link.
It was fault. Was using regular password I use to log in to NC.
I should have used the one “Create new app password.”
Made myself a note. Hope I can remember.

TL;DR - not on HA side.

OK, found the issue server side.

Upon fully resetting the integration and following all the steps I have determined that the NC side of the integration, the “Monitoring” app which provides the data, has broken in a way where it accepts connections and lists API endpoints (as per link above) but hangs when actually queried for the data.

My entire “app” subsystem was not responding. One app seems to have crashed and took the UI, management of apps and any app that queried statistics with it.

I am unsure which app took what app down, but upon a full reset several updates have rolled in to fix the crash. It is working now.
