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.


Thank you for your answer. From what I can understand, the Stream settings in NPM do not allow for the function performed by ssl_preread_server_name. That means I would have to modify things in the NPM container itself, right?
Sadly, I’m not familiar enough with Nginx Proxy Manager to know. But I would imagine that there must be a different way to achieve the same result.
BTW, when I read “NPM”, I first think of Node.JS Package Manager. The title of your post may be confusing, and you might consider editing it to spell out the name of Nginx Proxy Manager.
