Hello, We have enabled the Stripe payment gateway in our WHMCS installation. Stripe require TLS 1.2 protocol for transactions. We have installed a COMODO POSITIVE SSL certificate and through tests it appears TLS 1.2 is now supported, but perhaps doesn't get used by default. As a result, transactions are still failing with the following error; We are looking to hire somebody to fix this problem and force our website to use TLS 1.2 as default to ensure the Stripe payment gateway and transactions go through successfully. Below is some documentation relating to this issue; http://help.whmcs.com/m/troubleshoo...oting-unsupported-protocol-errors-tls-support https://support.stripe.com/question...tripe-integration-from-tls-1-0-to-tls-1-2#php If you believe you fix this issue in a timely manner, please contact me with a estimate for the cost of the work and a rough turnaround time for completing the work. This is a time sensitive task as the website was due to go live today. WebDev
