Symptoms
When the system automatically attempts to refresh the hostname certificate for your server, one of the following errors is received.
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.
The cPanel Store returned an error (X::UnknownError) in response to the request “POST ssl/certificate/whm-license/90-day”: Service Unavailable
Description
The AutoSSL provider rate limits how many orders can be accepted at any given time. When the rate limit is being enforced or during a maintenance event, "We were unable to process your request. Please try again later" will be the response to the SSL order. Developers are working to improve this scenario in a future release. We have identified that running our checkallsslcerts script at another time will result in a successful certificate installation.
Workaround
Running checkallsslcerts at a different time will succeed. Optionally, a cronjob can be set up for the root user:
30 20 * * * /usr/local/cpanel/bin/checkallsslcerts > /dev/null
