Doesn't work for Rocky Linux 9 as the Powertools repository has been changed to CRB.   In fact, I have not found a reliable guide to installing Poweradmin on Rocky Linux 9.

I modified the /etc/systemd/system/powerdns-admin.service file and changed the pat to gunicorn in the "ExecStart" to the full path in the powerdns-admin dir under opt. 

Ex: "ExecStart=/opt/powerdns-admin/flask/bin/gunicorn"

Now I am having a problem with Nginx. 

Getting a 503 gateway issue and this in the error logs.

@hybridblue did you ever figure this out? We're getting the same error as you regarding the upstream client.
