Docker CE || Unable to Install from a package

Hi Team,

I was trying to setup docker CE on Centos host. I was following - However the rpm download link provided in the link is not opening.

It always says as access denied -
Access Denied

Can you please help to resolve this. I tried to update the repository too using, which was resulting in timeout error always. My host is behind the internet, but i use proxy to bypass this. But still this is not working.
yum-config-manager --add-repo

Can you please help to resolve this issue.
