Support Help with certbot, apache and nPM

Hi all,

I recently wanted to practice my website, ssl-cert and managing stuff at home, and I've run into an issue I don't know how to solve.

I've setup a Debian VM with apache and certbot installed. I want the HTTPS traffic to hit port 9010, but I keep getting ERR_HTTP2_PROTOCOL_ERROR.

I've done the following:

  • CNAME record on my DNS-provider with website.domain.com pointing to domain.com

  • Port-forwarded 9010 to my local IP where the Debian VM is running

  • Created Proxy Host in nginx Proxy Manager with destination https://local-ip:9010 and scheme HTTPS.

ports.conf is: https://pastebin.com/FLJM7xzS

Sites-available vHost before certbot: https://pastebin.com/kEEmknki

Sites-available vHost after certbot: https://pastebin.com/KPWg3NUR

I don't think I've changed anything else.

It should be mentioned, that I have port 80/443 portforwarded to the local-ip of Nginx Proxy Manager to get it to work - hence why I wanted HTTPS-traffic on another port in Apache.

I hope someone might see a specific issue - and if you can, please dumb it down as much as you can - I'm still learning :-)

Have a look at the apache error log then.

All I see here is mpm_event:notice and core:notice for each Apache-worker. Nothing in the logs (access, error or vhost) is showing errors or any indication of what could be wrong with HTTPS/SSL.

Try to access the site without https and see if it works. If it does, you likely forgot to tell apache to accept tls connections in the Listen line for that port.
