- cpncrunch 12y agoHave you checked your web server logs? We had a problem a year ago where we were getting 403 errors (forbidden). It turns out that paypal's DNS was a bit screwy, so apache wasn't able to do a reverse dns lookup on the ip address, and it was therefore getting rejected by our server. I simply added the ip addresses of all of paypal's IPN servers to our Allow list, and we haven't missed any IPNs in the last year: Allow from .paypal.com Allow from 173.0.81.1 Allow from 173.0.81.33 Allow from 66.211.170.66
