HTTP exposed but not responding properly

General

Running Docker 1.9.1 on OpenSuse 42.1 (can’t upgrade at this time).

I have a Docker images that exposes a web application on port 8080. I can ssh into the container and access the application correctly from inside the container on http://localhost:8080/.

I run the container using

docker run -p 10000:8080 ...

and I would expect the web application being accessible on either

http://localhost:10000 or http://:10000

The port is open but the connection is being closed immediately.

sudo netstat -nap|grep LISTEN|grep -v LISTENING|grep 1000
root's password:
tcp        0      0 :::10000                :::*                    LISTEN      17375/docker-proxy

I can telnet to port 10000 but as said the connection is being closed immediately

docker --version
