问题
Although lots of people have asked this question and I have gone through many of them but unable to fix my issue. I think its simple but unfortunately I am stuck here.
I am able to hit my listener externally but not getting from IPN simulator. Getting the following error
any help is highly appreicated.
cheers!

Using a "raw" IP address in the target URL appears to be prevented by PayPal's IPN simulator; I've been testing it out and it seems that the simulator will only send a request if you use a domain name in place of the IP address.
So, instead of an address like http://1.2.3.4/test.php, if you have a domain name, you can set an A or AAAA record on the domain name to point to your IP address, and then replace the "naked" part of the URL - the 1.2.3.4 - with the domain name, like stackoverflow.com, so you'd end up with http://stackoverflow.com/test.php, which still should send you to the same endpoint as you were previously attempting to send the request to.
It's odd that this restriction would be in place, it could possibly be a bug that PayPal overlooked since I can't find any documentation on the subject, but that's one way to get around the restriction.

This has been confirmed by Paypal; pasted below from an incident I opened with them.
Hello,
That's correct, you need to use a domain name if you want to test with IPN simulator.
The way around it is to use either a LIVE or SANDBOX account and add the IPN URL with the IP address instead of a domain name.
ie: http://8.8.8.8/paypal/paypal-ipn.php
This will work outside of the IPN simulator.

Can you confirm that the IPN Simulator does not work with IP addresses as suggested by this post? Paypal IPN simulator issue
I am trying to test the G2 => G5 SSL certificate upgrade. Is there anyway around this or do I have to buy a domain just to perform testing?
Thanks Joe
