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

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
