Hello everyone, since this is my first post, i hope i am at the right place :D

I am hosting a webring for solarpunk websites and wanted to move this from the corporate hoster to the raspberry pi that was collecting dust in my cupboard to hopefully host it on solar in the future.

I installed nginx and put the website there, configured the portforwarding on my router (ports 80 and 443 to 80 and 443 on the pi) and gave it a fixed local IP. I then used ddclient to update the IP of the pi to the dyndns-API of my hoster (which i will keep for the domain for now). It is reachable through HTTP (solarpunk-ring.net) but refuses connection for HTTPS.

The Internet is full of AI-generated tutorials on how to self host and use a DynDNS-service, but i couldn’t find any info on this excact issue.

I assume it is not the DynDNS since that would otherwise also not refer to the correct IP with HTTP without S. Now i don’t know if it is the router or nginx or the pi itself refusing connection. The error log of nginx is empty. Ports are allowed in firewall, i also tried disabling the firewall, same error.

I have no idea what to check next and as i said, the ai-shit i get from my search engine isn’t helping either.

Sorry if this is the wrong place.
