IPN Verification URL giving 404 in Prod and Sandbox since 1/11/23

[Larrybud]

This started happening yesterday, 1/11/23. None of our environments have changed or been updated since the new year, IPNs have been working for years. When the flow posts back to Paypal per their documentation below, these two URLs are both 404s, therefore no verification ever takes place (tested and verified in both our test and live environments).

• https://ipnpb.sandbox.paypal.com/cgi-bin/webscr (for Sandbox IPNs)

• https://ipnpb.paypal.com/cgi-bin/webscr (for live IPNs)

Your listener sends the complete message back to PayPal using HTTPS POST.

Prefix the returned message with the cmd=_notify-validate variable, but do not change the message fields, the order of the fields, or the character encoding from the original message.

Send response messages back to PayPal:

https://ipnpb.sandbox.paypal.com/cgi-bin/webscr (for Sandbox IPNs)

https://ipnpb.paypal.com/cgi-bin/webscr (for live IPNs)

Hi,  

We are also reporting the same problem since 11th January 10am.  
May I ask if you have now resolved this issue? or found a solution from PayPal?
