Problem #

You see the following error:

curl: (51) SSL: certificate subject name '*.example.net' does not match target host name 'example.com'

You may see this when you test SSL on your server by running the following command:

curl --max-time 10 -v https://example.com

Cause #

This error indicates a cURL connection issue.

Solution #

Work with your system administrator or hosting provider to resolve the cURL connection error between the WHMCS server and the hosting server.
