Wordfence and Paypal IPN Notifications

Hi,

Here is where you can find the IP addresses of PayPal servers.

You can whitelist an IP that will bypass all firewall rules under Options.

Give that a try and see if it helps.

Thanks!

Hi,

PayPal IPN failure with a 503 error was my problem. WordFence was doing a super job protecting things, I just had the settings dialed up to be pretty aggressive. I went through trial and error and found that unchecking “Block IP’s who send POST requests with blank User-Agent and Referrer” did the job for me.

Hope that helps someone!
