SSL Protocol Error for Drupal Ubercart with Payment Gateway

Sunday, December 25, 2011

I received a dreaded "cURL error: Unknown SSL protocol error in connection to" when setting up the payment gateway for use in a Drupal Ubercart store recently. Oh noes! Here's how I fixed it.

Find the module ubercart > payment > uc_authorizenet

On line 558 (your mileage may vary) I added:
curl_setopt($ch, CURLOPT_SSLVERSION, 3); // Force SSLv3 to fix Unknown SSL Protocol error

Goodbye sweet, sweet error. I barely knew ye.
