I downloaded the latest docker engine 184.108.40.206 (31259) on my windows 10 machine. Then I wanted to try the swarm mode, so I created an Ubuntu VM using hyper-v, then I started the swarm mode on windows and tried to join the worker from ubuntu but I keep getting Connection refused.
I made sure all required ports tcp/udp are open on both the windows 10 and the ubuntu VM. But even when I try telnet on port 2377 it also fails.
I tried running “netstat -ab” command on the windows machine I do NOT see port 2377 listed.
To make sure problem is from docker, I created a windows app that listens on port 2377, and then i successfully connected to it from the Ubuntu machine. So port is not blocked by firewall.
I searched here and on the web and mostly found very old questions related to this.
