Failed to issue certificate: The Let’s Encrypt HTTP challenge failed - is .well-known/acme-challenge accessible in your webroot?
First, you need to check that you can actually access http://your-domain.com/.well-known/acme-challenge . If you cannot, then the issue is likely an
.htaccess rule blocking access. Try including the following lines at the top of your
RewriteEngine On RewriteRule ^.well-known - [L]
“The certificate could not be installed … Sorry the system admin has not enabled this feature”
Usually this means that a certain setting (allowcpsslinstall) is disabled. You may find this setting in WHM->Tweak Settings->Allow cPanel users to install SSL Hosts if they have a dedicated IP.
This setting is automatically changed during installation in version 0.4.3 and higher.
Rate limit error - too many certificates for this domain
Most likely, you have issued and deleted certificates of the same root domain too many times. These limits are quite low during the Let’s Encrypt beta period.
Rate limit error - too many registrations
The server may have hit a rate limit for too many new account registrations for a single IP address.
In this case, you should be able to proceed within 24 hours.
Icon not visible in cPanel
If the Let’s Encrypt icon is not visible in the cPanel list even though the link is present, this is most likely a caching issue. If forcing a refresh in your browser (Control+R) does not fix this, the plugin may need to be re-installed to refresh the cPanel icon cache for the plugin.
