Current Behavior

Running v9.5.21-ls106 under kubernetes I have this error:

...

I have the same error using a different container (built by me, based on rocky9), but not with the previous version.

This is the content of the /status page:

{"meta":{"rc":"ok","server_version":"9.5.21","server_running":false,"db_migrating":false,"up":false,"app_context_status":"UniFi Network Application is starting up...","app_context_message":"Please wait a moment"},"data":[]}

I had this issue earlier today. Downgrading mongo back to v7 was an easy fix.

services:
  mongodb:
    image: mongo:7.0.26-rc0-jammy
    container_name: unifi-db
