cPanel provides free SSL certificate to the domains and server’s hostname using AutoSSL feature. When the system automatically attempts to renew the hostname certificate for your server, you may receive the following error:
The cPanel Store returned an error (X::TemporarilyUnavailable) in response to the request “POST ssl/certificate/whm-license/90-day”: We were unable to process your request. Please try again later.
or similar error as follow:
The provider "cPanel (powered by Sectigo)" cannot currently accept incoming requests. The system will try again later.
cPanel team is actively working on this issue to identify and fix this problem. While they are working to resolve this issue, you can run checkallsslcerts script at another time and it should fix this problem.
Running checkallsslcerts at a different time will succeed, and, optionally, a cronjob can be set up for the root user:
30 10 * * * /usr/local/cpanel/bin/checkallsslcerts > /dev/null
