distribution: Server Gave HTTP Response to HTTPS Client error

Hi,

I am trying to run docker registry in insecure mode and when I am either trying to push or to pull. I get the following error:

This is command I used in order to run my registry:

# docker run -d -p 5000:5000 --restart=always --name registry -v `pwd`/data:/var/lib/registry reg
istry:2

~# docker push <IP>:5000/ubuntu
The push refers to a repository [<IP>:5000/ubuntu]
Get https://<IP>:5000/v1/_ping: http: server gave HTTP response to HTTPS client

This is the version info:

This is what I added into /etc/default/docker file DOCKER_OPTS="--insecure-registry <myip>:5000"

I tried edited that line with FQDN, IP address, --insecure-registry=<myip>:5000, and--insecure-registry http://<myip>:5000

Any ideas what could be causing this error?
