PuTTy remote port forwarding not working in v3.9.2
I have built a Docker container based on Alpine 3.9.2.
The container contains - among other things - an IDE from Jetbrains for Golang development.
From my local Windows station, using putty, I am trying to remote forward port 6000 to the container, so I can open the IDE on my Windows desktop.
However, “netstat -an” does not show port 6000 open in the Alpine v3.9.2 container.
I rebuilt the container using both Alpine 3.7 and Alpine 3.8 with no other changes in the Dockerfile(except the FROM alpine:x.x line). The port forwarding worked in both Apline 3.7 and 3.8 and thus I could open the Goland IDE on my Windows desktop.
Do you know why remote port forwarding is no longer working in v3.9.2 please?
