On running the docker command, I get following error:



docker run hello-world



Pulling repository docker.io/library/hello-world
docker: Network timed out while trying to connect to https://index.docker.io/v1/repositories/library/hello-world/images. You may want to check your internet connection or if you are behind a proxy..



I am getting following CURL output:

So how will i pull my machines now?



Now getting following message:

      On running the docker command, I get following error:



      docker run hello-world



      Pulling repository docker.io/library/hello-world
      docker: Network timed out while trying to connect to https://index.docker.io/v1/repositories/library/hello-world/images. You may want to check your internet connection or if you are behind a proxy..



      I am getting following CURL output:




      curl -v https://index.docker.io
      * Rebuilt URL to: https://index.docker.io/
      * Hostname was NOT found in DNS cache

      * Closing connection 0
      curl: (35) Unknown SSL protocol error in connection to index.docker.io:443


      So how will i pull my machines now?



      Now getting following message:



      Unable to find image 'hello-world:latest' locally

      Update(obfuscated keys):



      running following command gives output:
