Unable to connect to droplet via docker-machine

Asked by Mark S
I am attempting to run docker / docker-compose commands to start/stop/deploy docker images in my droplet, but am encountering the following error:
$ docker-machine ls
NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS
testmachine - digitalocean Timeout
I attempted to restart the machine and regenerate certs, but I still have the same problem. Any suggestions?

The problem was that I configured a firewall and did not open port 2376, which is the port that docker commands use to communicate with the remote docker machine. Adding a custom rule that allows TCP traffic over port 2376 resolved the problem.
