SSL throws a weird error in that if you have http (port 80) bound to one IP address [say an internal one] and you bind https (port 443) to a different IP address [say an external one] then SSL throws the following very undescriptive error:
SSL received a record that exceeded the maximum permissible length.
(Error code: ssl_error_rx_record_too_long)
To fix, edit your Apace configuration file in /etc/httpd/conf/httpd.conf (or similar) and make sure that both virtual hosts have the same IP address – job done 🙂
