Hi people, I have the followning scenario: I run a webserver behind my FritzBox's Router. Its a Ubuntu machine running umbraco with nginx/caddy as web proxy (both are not capable of getting lets encrypt) I get a dynamic ip address from my ISP, but the fritzbox has a static domain like this: (for privacy I changed some numbers) 4v5uae4x677op909.myfritz.net (its like dynamic dns, but I don't have to pay and it autoupdates it on every restart/public ip change) I created portforwarding from external 80 and 443 to my local 192.168.1.1 which is the server to 80 and 443. Now I created a CNAME from my domain danobe.dev -> 4v5uae4x677op909.myfritz.net . Problem is caddy for example says it needs to work a A/AAAA record. And I dont have one. And with letsencrypt and certbot I couldn't get it to run either. Domain was bought on google domains. I would like to host my private website on my computer at home, behind the fritzbox but with the public domain danobe.dev. Can anyone guide me into the right direction? That would be very kind! Thanks in advance, Daniel
