📖 TrueNAS SCALE Apps Showing Error After Reboot (Docker Bug)

Problem:

After rebooting TrueNAS SCALE, the Apps UI shows Error even though the Docker daemon is running normally.
Containers appear healthy in docker ps, but the Apps UI does not reflect the correct state.

Cause:

  • Known bug (NAS-133437).
  • The middleware times out if Docker takes too long to start during system boot.
  • Apps status is not rechecked automatically after Docker finishes starting.

Solution:

  1. Open the Shell or connect via SSH.
  2. Run the following command:
    midclt call -job docker.state.after_start_check &
    
  3. Wait about 10–30 seconds.
  4. The Apps UI will refresh and show correct status without needing a reboot.

Notes:

  • This command manually triggers the Apps system to re-check Docker containers.
  • No containers are restarted, only the status is refreshed.
  • Permanent fix expected in future TrueNAS SCALE updates after Dragonfish.
