I am trying to get a sandbox PayPal IPN working with the Coldfusion example shown here:
https://github.com/paypal/ipn-code-samples/tree/master/coldfusion
I've added the location of my IPN file to PayPal and the page is being called by it but all I get is a 'Connection Failure' message in the text file. The IPN file is being called from an https location so not sure what is wrong.
Any ideas?
