Docker Error : Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

When I build a dockerfile, I am getting the above error.

How we can fix this?

1. Login to host.
2. mkdir -p /etc/systemd/system/docker.service.d
3. /etc/systemd/system/docker.service.d/http-proxy.conf
4. Add the following line
[Service]
Environment="HTTP_PROXY=http://proxy.example.com:80/"
[Service]
Environment="HTTPS_PROXY=https://proxy.example.com:443/"
5. systemctl daemon-reload
6. systemctl restart docker
7. systemctl show --property=Environment docker

Try the build now, it will works!
