php - PayPal IPN on port other than 80

Question

Has anybody tried using Paypal's IPN on a port other than 80?

I'm trying to specify a URL like http://domain.com:8080/url/to/ipn.php but the IPN request isn't getting through.

If I hit the URL directly from my browser it works fine.

Answer 1

After doing multiple tests I was able to confirm that PayPal's Notification URL/notify_url can not contain a non-standard port number.

These urls will work:

http://my.website.com:80/ipnpage.aspx
https://my.website.com:443/ipnpage.aspx

These will not work:

http://my.website.com:81/ipnpage.aspx
https://my.website.com:82/ipnpage.aspx
