Problem #

You see the following error at Billing > Gateway Log while using the Stripe™ payment gateway module:

Network error [errno 35]: Unsupported SSL protocol version

Cause #

This error indicates a server configuration issue. The server is attempting a secure connection to Stripe using an outdated SSL protocol. Most providers now require connections via TLS for security purposes.

Solution #

To resolve this issue, work with your hosting provider or system administrator to ensure that remote cURL connections use TLS by default. You may also need to update your OpenSSL version.
