Let's Encrypt Addon and NOIP

I run HA on a virtual machine hosted on a synology NAS. DNS for my domain is hosted by NOIP. My router forwards port 8123 to the HA VM. I use the Let’s Encrypt addon to manage a SSL certificate for HA. There doesn’t seem to be support in the addon for renewing my cert using DNS challenge with NOIP so am usin the HTTP challenge.

I tried to configure HTTP challenge to use port 8124 (port 80 is used by a web server) but iy seems the configuration option to change the port doesn’t work. I am able to renew if I temporarily forward port 80 to HA instead of my web server. This is a pain and can’t be automated.

I would like help finding a path to automate renewal. Either by adding DNS challenge support for NOIP or by successfully changing the port for the HTTP challenge.

Thank you
