Paypal Advanced no longer working after upgrade to 3.0.1

I recently upgraded to Joomla 3.7.1 and Hikashop 3.0.1 and now I can't process payments via the Paypal Advanced plugin.

All of my merchant account information is correct in the plugin settings and I've verified the information with Paypals support. No changes were made to my plugin or paypal account prior to or after the upgrade.

The error I am getting is:
No response from PayPal's servers, please try again.

Notice: Undefined index: RESULT in /home/my/public_html/plugins/hikashoppayment/paypaladvanced/paypaladvanced.php on line 131

Notice: Undefined index: SECURETOKEN in /home/my/public_html/plugins/hikashoppayment/paypaladvanced/paypaladvanced.php on line 136

Some required information is missing or incorrect. Please correct the fields below and try again.

Error: Invalid Merchant or Merchant doesn't exist!

Hi,

This indicates an error when the plugin tries contacting PayPal.
Unfortunately, it doesn't give much information.
Try adding the code:
echo '<p>Error : ' . curl_error($ch).'</p>';
after the line:
echo "<p>No response from PayPal's servers, please try again. </p>";
in the file plugins/hikashoppayment/paypaladvanced/paypaladvanced.php
That should provide an error message with more information on why the connection was rejected by PayPal.

ok. i've added the code and tested it. i know get the following SSL error which doesn't make sense as we are using protocal TLS 1.2 (see attached)

No response from PayPal's servers, please try again.

Error : Unsupported SSL protocol version

After talking with godaddy i found out that we needed to upgrade open ssl and curlssl. they are installing the upgrade and i'll let you know if we still have an issue communicating with paypal.

Hi there!

I have exact the same problem here. Did you ever get it sorted out by any chance??

Thanks!
