After creating new Open Stack node with docker machine, reports Error checking and/or regenerating the certs

Checking connection to Docker...
Error creating machine: Error checking the host: Error checking and/or regenerating the certs: There was an error validating certificates for host "ip-address:2376": dial tcp ip-address:2376: i/o timeout
You can attempt to regenerate them using 'docker-machine regenerate-certs [name]'.
Be advised that this will trigger a Docker daemon restart which might stop running containers.

This is right after creating a new node with Open Stack. Even if I regenerate the certs it still reports an issue with the certs and I can’t even run docker-machine env

I’m on Windows using git-bash

I found out it’s because my Open Stack system didn’t have port 2376 open in its security group.
