We have been running EE for nearly 2 years now without issue. Late December all registrations successfully paid through Paypal started showing as Incomplete. This not only creates multiple steps on our administrative side to right things, but it is causing confusion for our students as they are not finishing on our Thank You page, but redirected back to Paypal as if they had not paid.

After combing through the forum posts here and attempting many of the suggested fixes, I contacted my host (Hostgator).
Their final response:

Hello,

We have come across this issue several times recently, it appears that PayPal is blocking connections originating from the primary network interface on the server. Until we know why this is happening and can resolve it we will need to have the PHP curl code use a secondary interface when making the connections. This can accomplished using something like the following to see the curl options:

curl_setopt($ch, CURLOPT_INTERFACE, ‘162.144.4.227’);

Though I am not sure where this will need to be placed within your source to make this happen, I believe that it is one of the following files:

[root@gator3190 /home2/ccti007/public_html/wp-content/plugins]# find -maxdepth 1 -type d -name ‘*espresso*’ -exec sh -c ‘grep -irl paypal {}’ \; | while read file; do grep -li curl $file; done
./event-espresso/gateways/paypal_pro/includes/paypal.nvp.class.php
./event-espresso/gateways/paypal_pro/includes/paypal.ap.class.php
./event-espresso/gateways/paypal/Paypal.php
./event-espresso/gateways/firstdata/settings.php
./event-espresso/includes/espresso-admin-status.php

But you will need to contact your developer to program this option in. Our scope of support for troubleshooting source code is very limited as per our terms of service.

Should this IP become blocked for any reason, please let us know and we will provide you another available one on the server until we have permanent solution in place.

I apologize for any confusion that this has caused.

Does this make sense to you? Which file, and where in that file, should their code be placed? I appreciate any help with this!
