docker - Error checking TLS connection: Error checking and/or regenerating the certs

Question

After I restarted my windows i cannot connect to docker machine running in Oracle Virtual Box. When i start Docker QuickStart Terminal every thing looks fine, it's coming up OK and it gives me this message:

docker is configured to use the default machine with IP 192.168.99.100
For help getting started, check out the docs at https://docs.docker.com

but when i do:

$ docker-machine ls
NAME      ACTIVE   DRIVER       STATE     URL   SWARM   DOCKER   ERRORS
default   -        virtualbox   Timeout

and:

λ docker images
An error occurred trying to connect: Get http://localhost:2375/v1.21/images/json: dial tcp 127.0.0.1:2375: ConnectEx tcp: No connection could be made because the target machine actively refused it.

also when i try to reinitialize my env., i get:

λ docker-machine env default
Error checking TLS connection: Error checking and/or regenerating the certs: There was an error validating certificates for host "192.168.99.100:2376": dial tcp 192.168.99.100:2376: i/o timeout
You can attempt to regenerate them using 'docker-machine regenerate-certs [name]'.
Be advised that this will trigger a Docker daemon restart which will stop running containers.

BTW, Regenerating certs also not helping. Any idea?

Thanks.

Please try regenerating certificates manually by:

docker-machine --debug regenerate-certs -f default

and check for any errors to fix, then try again:

docker-machine --debug env default

If it's failing on ssh, copy and paste that command into terminal to see what's the problem by adding extra -vv.

If you've got:

debug1: connect to address 127.0.0.1 port 64368: Connection refused

then your machine isn't running (check by docker-machine ls), so try:

docker-machine start

Then try to ssh to it via:

docker-machine -D ssh default
