Docker machine timeout - how to fix without destroying the machine?
This command worked for me with the digitalocean driver:
docker-machine ls -t 20
It seems as though the default timeout of 10 seconds was too short.
This is usually a problem related to the way you start and stop your machine.
You can solve it using
$ docker-machine stop default$ docker-machine start default$ docker-machine regenerate-certs default
Do not use docker-machine restart default because it will not refresh your networking configs.
Check if you are are using a proxy or VPN!
None of the above suggestions worked for me until I turned off my VPN and suddenly:
docker-machine.exe lsNAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORSdefault * virtualbox Running tcp://192.168.99.102:2376 v19.03.5
