I am using docker-engine to provision a docker-swarm cluster on DO, some days back it was working okay.
Today when I run the same command for creating the servers/nodes and master, it never finishes. it quits with,

Detecting operating system of created instance...
Waiting for SSH to be available...
Error creating machine: Error detecting OS: Too many retries waiting for SSH to be available.  Last error: Maximum number of retries (60) exceeded
Error creating machine: Error detecting OS: Too many retries waiting for SSH to be available.  Last error: Maximum number of retries (60) exceeded
Error creating machine: Error detecting OS: Too many retries waiting for SSH to be available.  Last error: Maximum number of retries (60) exceeded

On running docker-machine ls

Even when I try to regenerate the certs, it never finishes. I didn’t touch anything since it was running before. I have tried using different ubuntu variations but still gets the same problem.

Thanks guys for any suggestions or help.
