Unknown SSL protocol error in connection to xxxxxxxx.caspio.com:443

[ChadP]

I've created a token and played around with swagger with success.  When I try to make the same, simple request from a website using php curl, I get the following message:

Error: "Unknown SSL protocol error in connection to xxxxxxxx.caspio.com:443 " - Code: 35

I'm including the bearer token in the header.  Here is my code:

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL,"https://xxxxxxxx.caspio.com/rest/v2/tables");
        curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        'accept: application/json',
        'Authorization: bearer '.$variable_containing_my_token
        ));
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);    
        $response = curl_exec($ch);
        if( $response === false ){ echo 'Error: "' . curl_error($ch) . '" - Code: ' . curl_errno($ch); }
        curl_close ($ch);

What does this error indicate?  Should I be making this request another way?

Thanks!

If you run into this error you are probably running on an older server.  I've tested my code on a newer server and it works great.   I'm suspect I need an updated version of CURL or need to update NSS.

Are you saying by changing to a newer server you made it work?
