I just started receiving these errors and do not know the steps I should take to fix the issue.

I am using Docker For Mac:

• Version 17.03.1-ce-mac5 (16048)
• Channel: stable
• b18e2a50cc

I have the same errors, but they are not always reproducible. Sometimes running docker-machine ls again either has no errors, or a different machine shows the error message Get https://api.digitalocean.com/v2/droplets/{ID}: x509: certificate signed by unknown authority.

I just discovered docker-machine and thought I would give it a try, so I am following the docs for using it with DigitalOcean, but I, too, get the certificate error:

$ docker-machine create --driver digitalocean --digitalocean-access-token xxx kanban
Running pre-create checks...
Error with pre-create check: "Get https://api.digitalocean.com/v2/regions: x509: certificate signed by unknown authority"

$ docker -v
Docker version 17.03.1-ce, build c6d412e

$ docker-machine -v
docker-machine version 0.10.0, build 76ed2a6

I usually get the error on the first attempt and then the next attempt lets me in. Sometimes it's more than one time I get the error before I get in.

same problem

I have the same problem, no matter how many times I run the command. My Docker versions are:

%> docker --version
Docker version 17.06.1-ce, build 874a737
%> docker-machine --version
docker-machine version 0.12.0, build 45c69ad

Here is my console output:

%> docker-machine create --driver virtualbox myvm1

In my case, it looks like docker-machine trying to download the latest release of boot2docker.iso was causing the problem. I downloaded the .iso from github.com by navigating to the URL with my browser. After that, the 'docker-machine create .... ' command ran successfully.
