My crystal ball tells me you’re referring to the generation of a Let’s Encrypt certificate…

Did you open ports 80 and 443 on the router from the Internet to the internal ip of the Nethserver?

monitor.pension4u.app is registered on the internet and points to the ip 51.136.80.108?

That IP is a static public IP?
