[not a bug] IPN FATAL ERROR :: Transaction did not validate. ABORTED

[frage]

I can't see orders in zen cart 1.3.9c after paypal IPN payment
I have uninstall an reinstall Zencart IPN module and put on the log.

So i had the log attached to this thread
the last line is IPN FATAL ERROR :: Transaction did not validate. ABORTED.

I have try after changing paypal preference (language encodage to UTF-8) and obtained a second log.

Any ideas?
Best Regards,
Frédéric

I'm not sure why you're getting CURL problems. I'm guessing that the problems you have will go away if you get CURL communications working properly. That said, the fsockopen fallback should work properly, but apparently it doesn't for you ... I'm not sure why, as I can't recreate the problem here.

[frage]

Thank you for your answer.

So how could i control that curl is working well? should i install it as a modul on my linux server? Do you thing curl could be locked by iptables rules?

[frage]

I tried this and i have the following results

IPNCHECK.PHP - Version 1.3.9

CURL ERROR: Attempted connection on: https://www.paypal.com/cgi-bin/webscr

(7) couldn't connect to host

Trying direct HTTP on port 80 instead ...

IPN TESTING - Response Received via CURL -- COMMUNICATIONS OKAY



IPN ERROR :: Could not establish fsockopen:

Host Details = ssl://www.paypal.com:443 (110) Connection timed out

Trying again with HTTPS over 443 ...

IPN ERROR :: Could not establish fsockopen:

Host Details = https://www.paypal.com:443 (136289744) Unable to find the socket transport "https" - did you forget to enable it when you configured PHP?

Trying again directly over 443 ...

IPN ERROR :: Could not establish fsockopen:

Host Details = www.paypal.com:443 (110) Connection timed out

Trying again with HTTP over port 80 ...

IPN ERROR :: Could not establish fsockopen:

Host Details = httpwww.paypal.com:80 (110)

Trying again without any specified protocol, using port 80 ...

IPN TESTING - Confirmation/Validation response with fsockopen(): FSOCKOPEN() RESPONSE RECEIVED - Communications OKAY



Default method likely to be used for communications is: CURL, with the fallback method being FSOCKOPEN if possible.

Script finished.

Your CURL setup apparently doesn't understand how to communicate over SSL. In your server configurations you'll need to enable SSL for your CURL to work properly.

Seeing these messages I installed and configure SSL (even if i don't really use it) to see if this change something.

I continue having exactly the same messages with ipncheck

the following equivalent apache message can be more revelant

I can't anderstand where is really the problem. Any Idea?

[DrByte]

The problem is in your server's configuration.
I can't tell you how to install and configure PHP to use SSL -- that's up to the server administrator to do/know.
All I can tell you is that if you want to have secure communication to external services when handling payments (and yes, you need to do that even if you're not offering secure communications on the storefront for your customers' benefit), then you need to be sure your server can do it. A traditional webmaster is versed in these skills such as installing and compiling PHP and OpenSSL and enabling CURL etc. If you're taking on that responsibility for yourself, you're going to need to learn how to do that.

Is the port 443 open?

netstat -tulpn | grep :443 return me
tcp 0 0 0.0.0.0:443 0.0.0.0:* LISTEN 11386/apache2

and in iptables i can see
Chain INPUT
0 0 ACCEPT tcp -- eth1 * 0.0.0.0/0 0.0.0.0/0 tcp dpt:443
1725 95340 ACCEPT tcp -- * * 0.0.0.0/0 0.0.0.0/0 tcp dpt:443

Is Open SSL running ?

In my php info I can found:

Registered Stream Socket Transports : tcp, udp, unix, udg, ssl, sslv3, sslv2, tls

I continue having "connection time out" and no TCP connect with Curl (curl error 7)
