AutoSSL will return an error like the following when requesting a certificate.
[WARN] The system failed to acquire a signed certificate from the cPanel Store because of the following error: (XID kuh2k3) 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.
This error indicates that the AutoSSL backend servers were not able to process the request. This could be due to maintenance or could indicate that the servers are currently overloaded.
Rerun the AutoSSL check again at a later time.
