I switched to a UDM so I lost my HAProxy on my pfsense install. I was excited when I saw Tom released a video on something to fill the gap. I’m not having much luck with NPM doing a DNS challenge with my DNS hosted in cpanel though. Seems it’s using an old version of cpanel certbot plugin basted on this post - Cpanel setup · NginxProxyManager/nginx-proxy-manager · Discussion #3057 · GitHub. Hopefully the update submitted gets merged soon and it makes it into the docker image. I tried the suggested edit in my link but I’m still getting the same error.
Maybe it’s time to move DNS out of Cpanel to something else. I did manage to get this all working HAProxy though so it is possible with my host.
