today we tried to harden our SSL security and disabled SSLv3 support for our servers (which is recommended by Qualys SSLabs for example).
Sadly the WHMCS WP Integration Plugin doesn't work with SSLv3 as PHP cURL is set to use SSLv3.
Error as following:
WHMCS Integration: error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure
As SSLv3 is quite "deprecated" I would kindly ask you to (at least!) add Support for TLS or completely switch to TLS when connecting to https whmcs installations.
Just for the Futures sake!
Thanks and brgds!
