Services SSL not renewing as expected

We have been getting daily emails stating "The SSL certificate for "exim" on "our.domain.com" will expire in less than 30 days." We are now at 18 days left and the main cpanel certificate is still not renewing. What we have tried: - Not using Nginx - one post suggested that could be an issue with renewals. - Reboot'd the server. - Manually run as root: /usr/local/cpanel/scripts/upcp /usr/local/cpanel/bin/checkallsslcerts - This file does not exist: "/var/cpanel/ssl/disable_auto_hostname_certificate" - Clients sites we are using Let's Encrypt with no issues. - Cpanel is up-to-date CENTOS 7.6 kvm [-------] v78.0.23 - Cpanel domain has proper DNS and reverse DNS. - CAA records for our main domain and cpanel subdomain for LetEncrypt and Sentigo. All CAA records have removed to ensure they were not blocking in any way. We have had this VM for a few years with no issues until now. That is to say, the main SSL certificate always renewed properly on it's own in previous years. We now currently using a self signed certificate for our services, which is creating issues. Any suggestions on how to get this installation to upgrade? Adding output of /usr/local/cpanel/bin/checkallsslcerts The system will check for the certificate for the "cpanel" service.
