I am getting started with self hosting and one of the things I would love to host is a Signal TLS proxy using Docker.

Problem is that I have ports 80 and 443 taken by Nginx Proxy Manager (also in a Docker container), through which I forward to different services depending on the subdomain.

I tried modifying the docker-compose.yml file to use ports 9443 and 980 and have it working using a certificate created on NPM, but to no avail.

Being a beginner, it can well be that I don’t understand reverse proxies well enough, but that’s why, with your help I would love to take this opportunity to learn more.

Thanks in advance.
