Unknown SSL protocol error in connection to secure.authorize.net:443

[rfried498]

The software that we have been using for 3 years and all of a sudden it is throwing this error.  We have never seen this before.  Is there an issue with the server or did something change??

If your software is PHP using Curl, forcing SSLv3 may work for you. It solved the problem for me:

curl_setopt($ch, CURLOPT_SSLVERSION, 3); // Force SSLv3 to fix Unknown SSL Protocol error

I am having this same problem and have found that it is the resulted of a recent upgrade to php that was performed by my host.

The host provided me with avery similar snippet to the one that you used and my problem is that I cannot find a place to impliment it. I am using Joomla and VIrtuemart and after searching files for 2 days - I have stii not found the correct file(s). Where did you enter your code?
