5xx response errors on check all ssl certs

I have attempted to run the /usr/local/cpanel/bin/checkallsslcerts script on my server, but I have been receiving 503 and 504 errors like the following ones. Is there something that I should be doing differently? Under Manage Service SSL Certificates I have been receiving the yellow triangle for my services that "The certificate will expire in 14 days. Contact you Certificate Authority (cPanel, Inc.) to request a certificate renewal." message and would like to have the certificates renewed ahead of time ideally.
