Hello,
Sorry, the screenshot is not relevant.
You have to check and read the documentation link I gave you previously.
Please note that the Stripe plugin is a free plugin provided in Github ; the first commit made by myself and the HikaShop team participate and provide fixes.
Because the test explained in the documentation link has been made by our team and I repeat the procedure today on a local website (using PHP7) and it's working ; the plugin do have the TLS 1.2 support and no action is required.
So it means that the issue comes from your hosting ; which is not related to HikaShop or our support.
You have to see with your web hosting your SSL version and support of TLS1.2
