I am getting this error with the paypal_r plugin!? paypal_r ERROR: IPN validation error: Cannot validate PayPal IPN post: FOPEN [www.paypal.com] results to [ ()] Any ideas?
When this happened to me it was because curl(ssl) was not installed properly. Once it was re(installed) problem solved. If not go over to JLogica and raise a ticket (assuming you can't get CGI to fix it for you). Larry
Started Getting this Error Today I just started getting this error today. Paypal accepts payment but I never get the IPN back to give user access. I opened a ticket so we'll see... paypal_r ERROR: IPN validation error: Cannot validate PayPal IPN post: FOPEN [www.paypal.com] results to [ ()] The previous log record : CURL ERROR: (52) - GnuTLS recv error (-9): A TLS packet with unexpected length was received.
GnuTLS and Curl, needs to be rebuilt and only use OpenSSL I had this problem with curl on a Gentoo box. Solved it by rebuilding curl to not use GnuTLS but only OpenSSL. Run ldd on /usr/bin/curl If you see libgnutls.so.XX then it's using GnuTLS and needs to be recompiled.
