I am using letsencrypt's cpanel plugin for end users from a long time.
But, It seems cpanel.fleetssl.com is down from the last few days. Maybe 7 days or more.
Due to this down issue I am facing this issue.
[root@server1 ~]# yum -y update
This system is receiving updates from CloudLinux Network server.
