PayPal IPN Error and custom port IPN URL

问题:

My IPN URL is http://:85/ it has a custom port. This url is working fine but paypal is always giving me errors on its simulator and not calling my IPN on payments.

What would be causing this problem?

3. Look Selling Preferences which is third row.
4. Click the Instant Payment Notification Preferences link under Selling Preferences

The IPN listener needs to listen on the standard port for http(80) resp. https(443) otherwise it doesn't work... This is not specified in the documentation and it doesn't make sense so it is quite confusing!
