About the DDNS Let's Encrypt SSL

Hi,

getting SSL “automaticly” means your http requests are redirected automaticly to the https of your nextcloud domain, “jumping over” your non-SSL printer ports.

Especialy if your config says every request for *.asuscomm.com goes to https://myhomedomain.asuscomm.com

I think a clean virtualhost config and or letsencypt with certbot for everybody can solve your problem.
