I was sent the following email message during a regular LetsEncrypt certificate update. I reported it to my hosting company, but they found that the certificate had indeed been installed in spite of the error message. The error message is incorrect and should be fixed.
"The system failed to acquire a signed certificate from the cPanel Store because of the following error: (XID v7s6hg) 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."
Comment: it looks to me like this is an error that was detected by cPanel and handled properly. So the error message may be a real one (due to poor asynchronous programming in the LetsEncrypt client, for example), but should not have been passed out to the server owner. Correct certificate installation should not be accompanied by any error messages.
