I had a few clients report SSL did not renew their domains. I used the plugin
FleetSSL I purchased years ago, to install SSL.
I set up a new test server, and Comodo/Sectigo SSL would not install
5:41:47 AM SUCCESS “cPanel (powered by Sectigo)” HTTP DCV OK: cloud-de1.mytestserver.org
AutoSSL will request a new certificate.
5:41:47 AM The system will attempt to renew the SSL certificate for (cloud-de1.mytestserver.org: cloud-de1.mytestserver.org).
5:41:56 AM The “cPanel (powered by Sectigo)” provider cannot currently accept incoming requests. The system will try again later.
The system has completed “cloudde1”’s AutoSSL check.
5:41:56 AM The system finished checking 1 user.
I switched to Service Provider to
Let's Encrypt, as mentioned by
@cPRex, and SSL was installed instantly.
5:55:36 AM SUCCESS “Let’s Encrypt™” HTTP DCV OK: cloud-de1.mytestserver.org
AutoSSL will request a new certificate.
5:55:36 AM The system will attempt to renew the SSL certificate for (cloud-de1.mytestserver.org: cloud-de1.mytestserver.org).
Certificate #1: “cloud-de1.mytestserver.org” only
Reusing certificate order from DCV (Domain Control Validation) …
5:55:37 AM Installing “cloud-de1.mytestserver.org”’s new certificate …
5:55:38 AM SUCCESS Success!
5:55:38 AM The system has completed “cloudde1”’s AutoSSL check.
5:55:38 AM The system finished checking 1 user.
Emptying Let’s Encrypt’s DCV (Domain Control Validation) cache …
It sounds like Comodo/Sectigo SSL is no longer reliable, and cPanel needs to use Let's Encrypt as the default Service Provider instead!?
