I think it might be a Firewall issue because even docker run hello-world fails:

Unable to find image 'hello-world:latest' locally latest: Pulling from library/hello-world e6590344b1a5: Retrying in 1 second docker: error pulling image configuration: download failed after attempts=6: tls: failed to verify certificate: x509: certificate signed by unknown authority. See 'docker run --help'.

I`ll check if thsi is true and will update the topic.
