Hey everyone, I’m new to cloud computing and just set up Nginx Proxy Manager (NPM) on an Oracle Cloud instance using Docker. Everything works fine when I access my public IP with a port number, but as soon as I add an SSL certificate (using DESEC as my DNS provider), my domain stops loading.

What I’ve Done So Far:

Installed Docker + Nginx Proxy Manager on my Oracle instance Opened the necessary ports in Oracle Cloud firewall and checked my local firewall settings Used Let’s Encrypt for SSL, and the certificate appears valid

The Issue: Without SSL: My proxy works fine, and I can access services via the domain. With SSL enabled: The site doesn’t load at all. If I remove the SSL certificate, everything starts working again

Has anyone encountered this before? What else should I check?
