TLS verification failed on a new machine

[thefrana]

Hi, I was trying setup Docker Swarm according to this repo https://github.com/BretFisher/dogvscat, but when run basically any Docker command (eg. docker ps or docker stack deploy) I encouter an error:

The server probably has client authentication (--tlsverify) enabled. Please check your TLS client certification settings: Get "https://<ip>:2376/v1.40/containers/json": remote error: tls: bad certificate

I also tried solutions listed in this issue https://github.com/docker/toolbox/issues/255, but none of them worked for me. I even tried regenerate certificates, but with no success.

$ docker-machine env <machine>
export DOCKER_TLS_VERIFY="1"
export DOCKER_HOST="tcp://<ip>:2376"
export DOCKER_CERT_PATH="/home/<username>/.docker/machine/machines/<machine>"
export DOCKER_MACHINE_NAME="<machine>"
# Run this command to configure your shell: 
# eval $(docker-machine env <machine>)

Current workaround is

$ export DOCKER_HOST=ssh://<username>@<ip>

Any help will be much appreciated

Thanks
