Hi Sorcerer Stone, So the netstat output and the `docker container ls` helps us understand what is happening. So I'll repeat the details here.

And only nginx is doing port-forwarding. nginx is in fact a reverse proxy, meaning that most likely you're accessing nginx in order to contact all the other containers. Therefore, if you can access 9443 and 9080 from the VM then you're good (from the perspective of the VM). So you'll notice that the docker container with image name jodogne/orthanc-plugins:latest is listening on port 4242 (but it's not forwarding port 4242!). I believe you're calling this container "AppDock" (and AppWin is running on the host). As you can see by the container, it is not forwarding the port. You should check the nginx container and see if it is proxying communication to AppDock. So basically, the host "AppWin" cannot reach docker container "AppDock" because how is it supposed to reach it? Basically, AppDock needs to do port-forwarding (so that the VM can reach the container) or AppWin should try to go through the reverse proxy, nginx, to reach the docker container service listening on port 4242. -- This mailing list is governed under the HashiCorp Community Guidelines - https://www.hashicorp.com/community-guidelines.html.
