Answer 1

NTML PROXY AND DOCKER 

If your company is behind MS Proxy Server that using the proprietary NTLM protocol.

You need to install **Cntlm** Authentication Proxy

After this SET the proxy in 
/etc/systemd/system/docker.service.d/http-proxy.conf) with the following format:

[Service]

Environment=“HTTP_PROXY=http://<<IP OF CNTLM Proxy Server>>:3182”

In addition you can set in the .DockerFile
export http_proxy=http://<<IP OF CNTLM Proxy Server>>:3182
export https_proxy=http://<IP OF CNTLM Proxy Server>>:3182
export no_proxy=localhost,127.0.0.1,10.0.2.*

Followed by:
systemctl daemon-reload

systemctl restart docker

This Worked for me

Answer 2

In my case, stopping Proxifier fixed it. I added a rule to route any connections from vpnkit.exe as Direct and it now works.

Answer 3

Just to add, in case anyone else comes across this issue.

On a Mac I had to logout and log back in.

docker logout

docker login 

Then it prompts for username (NOTE: Not email) and password. (Need an account on https://hub.docker.com to pull images down)

Then it worked for me.

Answer 4

1. ReCheck Proxy Settings with following commands

   docker info | grep Proxy

2. Check VPN Connectivity

3. If VPN not using CHECK NET connectivity

4. Reinsrtall Docker and repeat above steps.

5. Enjoy

Answer 5

For me the problem was solved by restarting the docker daemon:

sudo systemctl restart docker
