Additional entrypoint for docker container


For a special service I was asked to set up SSL on port 4433.
This was the nginx configuration I was sent:

server {
        server_name your.domain.tld;

        server_tokens off;
        default_type application/json;
        ssl_session_cache shared:SSL:32m;
        add_header Strict-Transport-Security "max-age=63072000; includeSubdomains" always;
        add_header X-Content-Type-Options "nosniff";
        add_header X-XSS-Protection "1; mode=block";

        location /info {
                allow all;
                proxy_pass http://localhost:8080/info;

        location / {
                access_log off;
                include /etc/nginx/tb-balancer.conf;
                proxy_pass http://localhost:8080;

    listen [::]:4433 ssl http2;
    listen 4433 ssl http2;
    ssl_certificate /path/to/your/ssl/fullchain.pem;
    ssl_certificate_key /path/to/your/ssl/privkey.pem;

For traefik I have set up an additional entrypoint for the port 4433 called "tb".

Within the service I have added both websecure and the additional entrypoint "tb"

The service is reachable on websecure "" but not ""

Here the dashboard

What might I have done wrong?

Thank you!

Hello @antonionardella,

When you say the service is not reachable, what do you mean?

  • Can you connect to (is the TCP port open)?
  • Does provide a certificate (is it the correct certificate)?
  • Does respond to the request (is it a 404 response? non 404?)

Each of those may indicate different issues.

Hello and thanks for the reply.

The port 4433 is open.
It does not provide a certificate
It does not reply with 404

All I get is connection timeout

Although the server is not listening to the 4433 port

Hello @antonionardella,

If you are running Traefik inside docker, you also have to bind the port in docker.

Did you add 4433:4433 to your ports section of your compose file?
