I try to run sudo yum update but getting error : Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock error was 14: curl#52 - "Empty reply from server"
I already added a proxy configuration in /etc/yum.conf since the connection to the Internet will be using a proxy server but still failed. I am using Centos, Linux 7 and I'm still new to this.
TQ
