Can't uninstall app and mongodb is not reachable

[mendoksai]

Hi Cloudron team,

I have a stale app entry in the dashboard for “Family Chat (Rocket.Chat)”.
The app appears to be already gone at the container/data level, but it still remains in the dashboard as an errored app.
Uninstall fails with a foreign key constraint error referencing box.appAddo....

While investigating, I found that cloudron-support --troubleshoot reports:

• No pending database migrations
• box v9.1.6 is running
• Service mongodb is not reachable

The MongoDB logs suggest it is not just “hanging”, but crashing during startup:

• WiredTiger-related stack frames appear during startup
• mongod aborts
• Cloudron then repeatedly gets MongoNetworkError: connect ECONNREFUSED 127.0.0.1:27017

This started after a hardware RAID controller issue on the server. Hetzner has already replaced the RAID controller successfully and the server is back online.

My current understanding is:

• MongoDB service startup is failing at the WiredTiger/storage layer
• the stale app entry may be a secondary symptom
• uninstall cannot complete because the addon/service cleanup is incomplete

Could you please advise the safest supported recovery path?

Thanks!

I had to remove the mongodb as well. Now it's okay. the app has gone from dashboard.

Ohh no now it's happening for another app after update the app itself.

This is Kuma.

Is there a way to stop update apps also all at once?

Luckily I have backup, I'll restore to previous version.

[mendoksai]

I disabled all updates for now. Thank you, you may resolve this ticket too.

Interesting ... I restored the app but no data is recovered.. how is this possible ... and I can't attach screenshots here it says dimensions are too big ... it's not big actually.

From that error log it seems that other app is sqlite related: "[DB] INFO: Database Type: sqlite"
Is this all related to the same rocket.chat app uninstall issue or some other problem?

For mongodb not running, with latest Cloudron we stop unused services, so this sounds actually correct.
