Hi,

I’m getting this error

> Error checking TLS connection: Error checking and/or regenerating the certs: There was an error validating certificates for host “192.168.99.102:2376”: tls: DialWithDialer timed out

while trying to create a docker machine on Mac.

I’m running  
\> $ docker -v  
\> Docker version 17.03.1-ce, build c6d412e  
\> $ docker-machine -v  
\> docker-machine version 0.10.0, build 76ed2a6

> MAC OS 10.12.3 and VirtualBox 5.0.10 r104061

I have tried re-generating the certs, re-installing VM and docker and restarting the laptop, but still not able to fix this issue.

I am able to ssh to the docker-machine, but

> docker-machine create --driver=virtualbox vbox-test  
> docker-machine env vbox-test  
> eval “$(docker-machine env vbox-test)”

fails with the above error message

Any fix for this?
