Hi there @carstenh,

Are your running this insde a Docker container or directly on your host?

I could suggest a couple of things here:

  • First run a netstat to check if your service is binded on localhost only:
netstat -plant | grep 3050 

If the output that you get looks like thins:

tcp        0      0  *               LISTEN      -

Then you need to make sure that you update your config to bind on instead.

  • Another thing that you could do is rather than binding on is to setup an Nginx reverse proxy and forward the traffic from port 80 to port 3050.

You can do that by following the steps here:

Note yo only need to follow the “Set Up Nginx as a Reverse Proxy Server” step.

Hope that this helps!
