Your network is broken and until you work out how it is broken and fix it, you will not get anywhere. I'd suspect an external web proxy stopping you from accessing the outside world.

It´s a Firewall, this cent os is installed on a Hyper-V server and others vms are working fine

If you cannot use curl to retrieve the mirrorlist entry then something is between you and the server and stopping the traffic. And since you're the only one affected, I'd bet it's your side not CentOS.

Thanks a lot for your help!

It was the firewall blocking because centos didn´t authenticate it.

validate dns config

cat /etc/resolv.conf


try

nslookup yahoo.com


Do you get response ?


setup internal YUM repo as good practice
