Trying to setup remote access to the server WebGUI using a certificate, but seem to be having issues. Would love to do it somehow with a duckdns account and letsencrypt. I thought I had everything setup properly but obviously not because it doesn't work. After modifying my containers, when I enter my duckdns domain, I only come to a page that says something like the server is being worked on. I think it might be a port forwarding issue, but I don't know how to get around it. I have to forward port 80 and 443 in my router, but I already have rules for ports 80 and 443 in my router to securely log into nextcloud so I can't make a new rule for port 80 and 443. So that leads me to two questions:
1.) Is their a tutorial anywhere that explains exactly how to setup remote access to the WebGUI?
2.) Or is it safe to change the default port numbers under 'General Settings' to something other than 80 and 443 without it impacting any of the docker containers I already setup using Techno Dad's youtube videos? I could try changing them myself, but i'm worried about getting myself locked out of the local WebGUI by messing with settings i'm unsure of so I want to make sure it's safe first.
Thanks for any advice....
