Vikunja instance running into variety of errors

[shrey]

My Vikunja has sort of stopped functioning.

When i try to login, i either get 405 error, or 502.
Have ensured that login credentials are working, network connection from local to cloudron is ok and that the Vikunja app is up and running with enough resources.

Also, i keep seeing this error in the console:

Feb 25 09:56:10 172.18.0.1 - - [25/Feb/2023:04:26:10 +0000] "GET /api/v1/info HTTP/1.1" 502 166 "-" "Mozilla (CloudronHealth)"
Feb 25 09:56:10 2023/02/25 04:26:10 [error] 130#130: *574 no live upstreams while connecting to upstream, client: 172.18.0.1, server: default_server, request: "GET /api/v1/info HTTP/1.1", upstream: "http://localhost/api/v1/info", host: "my-vikunja-domain"

What could be the issue here and how do i go about diagnosing it?

Thanks.

@shrey the vikunja app has some frontend files and then a separate backend server (all part of the same app). The error 502 indicates that the backend has stopped for some reason.

I would restart the Cloudron app and have a look at the logging during startup if login still does not work afterwards.

What makes me wonder however is that ad far as I remember the Cloudron app pings the health endpoint of the backend for the health check. So if the backend does not respond, the app should be marked as non responsive in the dashboard.

Hi @fbartels

Restarting the app is not resolving the issue.

Here's the log file starting from the moment the app is restarted:

@shrey the relevant error seems to be:

So the server throws an error during startup (and then gets restarted). I had a short look on the vikunja forum, but could not find a similar report. I recommend to post the above error message along with version information at https://community.vikunja.io/

@fbartels Thanks for the triage!

Will raise a ticket there.

Hi @fbartels

So, i did hear back from them (https://community.vikunja.io/t/vikunja-self-host-cloudron-not-working/1187/4)

The recommendation is to disable redis, as it's currently buggy, and will be removed in a future release.

But, i'm unable to do so at my end, because even though i set cache & redis to disabled, in the config.yaml, the config gets reset to true once the app has been restarted.

[fbartels]

@shrey ah yes, the two points in the app that use redis are indeed hardcoded in the startup script. Let me make a pr so that @staff only needs to merge and do their normal release procedure.

@fbartels thanks, I will make a new package.

[girish]

Done. I have published a new package.

[shrey]

@girish Thanks for the quick update!

The app is finally working again.
