I have latest Docker version 18.06.0 installed on CentOS 7.
My server is in a corporate network so using a proxy server to access the registry.
I have added proxy settings as per docker documentation.
But finally adding proxy settings in worked partially. i.e. now docker is using proxy to pull the image before it runs.
But now it fails giving following error:
$ sudo docker run hello-world
Unable to find image ‘hello-world:latest’ locally
docker: Error response from daemon: Get https://registry-1.docker.io/v2/: proxyconnect tcp: net/http: TLS handshake timeout.
Also, the login fails:
$ sudo docker login --username=XXXX
Password:
Error response from daemon: Get https://registry-1.docker.io/v2/: proxyconnect tcp: EOF
- My proxy is pretty fast. When I’m using it to download anything from the internet using wget or curl I see 90 to 100Mbps speed.
- Other applications utils on my machine such as yum are using this proxy perfectly and it works well.
Now I don’t know why only Docker has a problem in downloading the images.
The details of installation and configuration are as follow:

Docker proxy config:
$ cat /etc/systemd/system/docker.service.d/https-proxy.conf
[Service]
Environment=“HTTP_PROXY=http://pqr.corp.xxx.com:8080”
Environment=“HTTPS_PROXY=https://pqr.corp.xxx.com:8080”
Environment=“NO_PROXY=localhost,127.0.0.1”
after adding this configuration I have already done
sudo systemctl daemon-reload
sudo systemctl restart docker
Looking for specific help.
I have gone through most of the posts on TLS Handshake Timeout issues but didn’t get any answer or suggestions working for me.
My proxy is fine and docker is using it. I don’t understand why it gets that nasty timeout.
