I am running a docker binary I built (following this) and when I do a docker pull, I get this error.

Error response from daemon: Get https://registry-1.docker.io/v2/: proxyconnect tcp: tls: oversized record received with length 20527

I have set the proxy as mentioned here, and the pull works fine with the default daemon and the same proxy settings. Changing DNS to 8.8.8.8 doesn't seem to help.

ping registry-1.docker.io

results in 100% packet loss.

docker info gives this

What is your Docker version?

With Docker version 17.09.0-ce, build afdb6d4, it was working for me, but after yum update to get Docker version 18.06.0-ce, build 0ffa825, I had the same problem.

Could you please check your /etc/systemd/system/docker.service.d/https-proxy.conf ? I think you have configured like this :

HTTPS_PROXY=https://user:pwd@proxy:port

But now, try to configure HTTPS_PROXY with http protocol instead of https protocol :

HTTPS_PROXY=http://user:pwd@proxy:port
