[SOLVED] OpenPanel – admin service failed with no error logs

When the OpenAdmin service fails without logging any errors, you can inspect the service’s status to get clues on the failure source. Running the command below will show the status and recent logs of the OpenAdmin service:

service admin status

If you encounter a service failure similar to the following output, it indicates a problem with starting the service, possibly due to a misconfiguration or an already running process:

× admin.service - OpenAdmin
     Loaded: loaded (/etc/systemd/system/admin.service; enabled; vendor preset: enabled)

To manually start the process and identify the issue, use:

gunicorn -c /usr/local/admin/service/service.config.py app:app

If the error “Already running on PID XXX (or pid file ‘adminpanel’ is stale)” appears, it suggests a process conflict or a stale PID file. Resolve this by terminating the conflicting process:

kill -9 PID_HERE

After addressing the conflict, restart the OpenAdmin service to apply the changes:

service admin restart

Following these steps should successfully restart the OpenAdmin panel, and it will be accessible again:

opencli admin on

This procedure provides a straightforward way to resolve service failures for OpenAdmin by identifying and eliminating process conflicts and ensuring the service is correctly restarted.
