Connection refused when pulling docker image on windows server

Question

After installing docker on a windows server i got the following error when pulling a image with docker run hello-world command:

Error response from daemon: Get https://hub.docker.com/v2/: dial tcp 52.6.16.15:443: connectex: No connection could be made because the target machine actively refused it.

Answer 1

The problem was that the proxy was blocking the request.

After some headaches, i finally got how to setup up proxy for docker on windows server from the right guide:

Using powershell in elevated mode:

1. Set environment variable to HTTP_PROXY environment variable

[Environment]::SetEnvironmentVariable("HTTP_PROXY", "http://username:password@proxy:port/", [EnvironmentVariableTarget]::Machine)

May not need to specify credentials, if your proxy don't require it.

2. Restart docker

 Restart-Service docker

Now it should run:

docker run hello-world
