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      0 127.0.0.1:3050            0.0.0.0:*               LISTEN      -

Then you need to make sure that you update your config to bind on 0.0.0.0:3050 instead.

Another thing that you could do is rather than binding on 0.0.0.0:3050 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:

https://www.digitalocean.com/community/tutorials/how-to-set-up-a-node-js-application-for-production-on-ubuntu-16-04#set-up-nginx-as-a-reverse-proxy-server

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

Hope that this helps! Regards, Bobby
