Paypal Express Checkout - Curl or SSL Issue

I'm trying to post a message but keep getting the cloudflare blocked message, please help?

Since I can't post it here, I have put the issue up in a simple file online, if this isn't allowed go ahead and remove it: http://extrememarketingprogram.com/payp ... -issue.htm

Trying to troubleshoot a Paypal Express issue on a new install of opencart 2.1.0.2. I have Paypal express in sandbox mode. When I get to step 6 and press "confirm", it takes me right back to step 2. I see this error code in the logs of opencart:

After some research, it seems to be curl/ssl related. Via SSH the command "curl https://api-3t.sandbox.paypal.com" throws "curl: (35) SSL connect error". Forcing curl to use Tls seems to work: "curl -1 https://api-3t.sandbox.paypal.com" gives "a page not found error", so it's getting past the SSL issue.

So I figured if I could force curl in php to use TLS, I should be fine. So I edited "catalog/model/payment/pp_express.php" and added "CURLOPT_SSLVERSION => "CURL_SSLVERSION_TLSv1_2" to the $defaults array. Same error in the logs. So I tried adding "CURLOPT_SSL_CIPHER_LIST => 'TLSv1'" and got a new error:

I'm running centos 6.5 on a dedicated server. I tried "yum update curl" and "yum update openssl" in case it was those, but that didn't help. I could update centos but this is a production box with 100 or so site on it and would rather not break anything. If anyone has any ideas what to try next, I would appreciate it in advance.

Thank you, Mike Rogers
