Common causes and fixes for Let’s Encrypt SSL errors in cPanel

While the installation process for Let’s Encrypt SSL certificates through cPanel is generally straightforward, there can be occasional errors. Here are some common troubleshooting steps to address potential issues:

Domain Verification Error

If you receive an error message indicating domain verification issues, ensure your domain name is correctly pointed to your cPanel server’s IP address using a tool like DNSchecker. Propagation times for DNS changes can take effect within a few hours.

Wait for DNS propagation to complete and then re-issue the Let’s Encrypt certificate. Additionally, consider unchecking the “mail.yourdomain.tld“ entry on the SSL list within cPanel, as this can sometimes interfere with verification.

Access-Blocking Rules

The error message “Invalid response from http://domain.tld/.well-known/acme-...” might suggest access-blocking rules within your website’s .htaccess file are preventing Let’s Encrypt from verifying ownership of your domain.

Access your website’s files using the cPanel File Manager. Locate the .htaccess file and rename it to something like .htaccess_disabled to temporarily disable it. Re-attempt the Let’s Encrypt SSL certificate issuance process. Remember to re-enable your .htaccess file (if applicable) after successful certificate installation.

Rate Limit Reached

The error message “Error creating new order: acme: error code 429 or too many failed authorizations recently” indicates that you have exceeded the issuance rate limit for Let’s Encrypt certificates. This typically occurs due to multiple unsuccessful attempts within a short period.

Unfortunately, there’s no way to bypass this rate limit. You will need to wait for 7 days before attempting to re-issue the Let’s Encrypt certificate for your domain.

By following these troubleshooting steps and considering the additional points, you can effectively address common errors and successfully install Let’s Encrypt SSL certificates on your cPanel website.
