CentOS release 6.6 running httpd & php for webserver
We have a working paypal IPN processing script, however when we went to move it to a new directory and test in the paypal IPN simulator we got the error:
"IPN was not sent, and the handshake was not verified. Please review your information."
Trying to debug this led us to: IPN was not sent, and the handshake was not verified. Please review your information.
Following the advice in the stockoverflow post when we run: openssl s_client -connect api-3t.sandbox.paypal.com:443 -showcerts -CApath /etc/pki/tls/certs/
We get: Verify return code: 20 (unable to get local issuer certificate)
We have installed the g5 certificate: [root@li375-212 testing]# awk -v cmd='openssl x509 -noout -subject' '/BEGIN/{close(cmd)};{print | cmd}' < /etc/pki/tls/certs/ca-bundle.crt | grep "G5" subject= /C=US/O=VeriSign, Inc./OU=VeriSign Trust Network/OU=(c) 2006 VeriSign, Inc. - For authorized use only/CN=VeriSign Class 3 Public Primary Certification Authority - G5
However we still get the Verify return code: 20 (unable to get local issuer certificate) after running the openssl command listed above
