This is because CentOS 7 has reached the end of its life. You need to modify your configuration to usehttps://vault.centos.org/ instead of the main mirrors.

Edit /etc/yum.repos.d/CentOS-Vault.repo, jump down to the end of the file, where you see c7.9.2009, and enable the sections base, updates, and extras for that version. Insert enabled=1. (This matches the default enables for the original distro.) c7.9.2009 is the last release available.

Edit /etc/yum.repos.d/CentOS-Base.repo and add enabled=0 to all sections. (Some optional sections already have this.)
