- Plesk Onyx for Windows
Note: This article has the reference to the issue with the fix available:
"A failed certificate installation led to exhausting the Let’s Encrypt rate limits for a domain,
which resulted in inability to renew the certificate."
- Let’s Encrypt 2.2.0 11 July 2017
Creation of subdomains with mixed letters leads to auto-renew of the cert repeatedly and cause the error:
Error Creating new cert :: too many certificates already issued for exact set
Failed certificate installation to Plesk exhausts LE's domain rate limits. This is Let's Encrypt extension bug with ID EXTLETSENC-198 that will be fixed in future updates.
As a workaround, download and unpack a temporary fix .
The certificate renewal can be enforced using the following command:
# plesk bin extension --exec letsencrypt renew.php SubDomain.example.com
