docker: Error response from daemon: Get https://registry-1.docker.io/v2/: Service Unavailable. IN DOCKER , MAC [closed]

Here are few suggestions:

1. Try restarting your Docker service.

2. Check your network connections. For example by the following shell commands:

   </dev/tcp/registry-1.docker.io/443 && echo Works || echo Problem
   curl https://registry-1.docker.io/v2/ && echo Works || echo Problem
   

3. Check your proxy settings (e.g. in /etc/default/docker).

If above won’t help, this could be a temporary issue with the Docker services (as per Service Unavailable).

I had this problem for past days, it just worked after that.

You can consider raising the issue at docker/hub-feedback repo, check at, Docker Community Forums, or contact Docker Support directly.
