IPN paypal failed

Hi

for one week, I’ve a Warning from Paypal about IPN. It seems that some informations cannot pass between Paypal and S2member, like Automatic EOT Time, and Paid Subscription Gateway. I’ve read a lot on the Net, but didn’t found something relevant for me. I tested my server with the tool provided here and everything is fine. Configuration of Paypal and S2member are the same, for exemple, Paypal API Username, Password, signature, IPN URL, Auto return URL. I never changed these parameters who always worked fine until now.

I tried contacted Paypal, and they said that the communication was ok between the server and Paypal, but that they become a blank HTTP answer and that’s probably a bug in the script.

paypal-api.log says :
——– Output string/vars: ( Tue Apr 2, 2013 7:39:09 pm UTC ) ——–

array (
‘__error’ => ‘Error. Please contact Support for assistance.’,
)

paypal-ipn.log says :
array (
‘s2member_log’ =>
array (
0 => ‘Unable to verify $_POST vars. This is most likely related to an invalid configuration of s2Member, or a problem with server compatibility.’,
1 => ‘If you’re absolutely SURE that your configuration is valid, you may want to run some tests on your server, just to be sure $_POST variables are populated, and that your server is able to connect/communicate with your Payment Gateway over an HTTPS connection.’,
2 => ‘s2Member uses the `WP_Http` class for remote connections; which will try to use `cURL` first, and then fall back on the `FOPEN` method when `cURL` is not available. On a Windows® server, you may have to disable your `cURL` extension; and instead, set `allow_url_fopen = yes` in your php.ini file. The `cURL` extension (usually) does NOT support SSL connections on a Windows® server.’,
3 => ‘Please see this thread: `http://www.s2member.com/forums/topic/ideal-server-configuration-for-s2member/` for details regarding the ideal server configuration for s2Member.’,
4 => ‘array (
‘s2member_paypal_notify’ => ‘1’,
)’,
),
)

paypal-rtn.log : everything seems ok

Thanks in advance for your help.

Do them all, but especially the server check one. :)

Hi Eduan,

and thank you for your answer. I already tested the server and everything was ok and I didn’t make any change to my blog (no plugin update, no new plugin, no theme update…). Meanwhile I read other people who had the same problem as me, saying that some ports of their site were closed due to an attack. This was among the others, the port 443.

I contacted my provider about this and they took contact with Paypal. Paypal said that my server was blacklisted by AT&T. My provider took then contact with AT&T and these ones said that there were no blacklist on servers of my provider.

My provider said that the origin of my problem is probably at Paypal… This is crazy…

Indeed. I’m afraid I can’t provide any help with this, but at least you know what the problem is. :)

Hi Eduan

thanks for your answer. I become crazy. Paypal doesn’t answer to my requests. I’m thinking to move to google checkout, using s2member pro but I’m still note 100% sure that the problem strictly comes from Paypal and there is not a problem in s2member too.

My question is : is it possible to try for free for a few days s2member pro to check if my problem is resolved using this plugin and google checkout ?

Thanks for your answer.

Hello Jay,

I’m afraid s2Member doesn’t have a trial period.

And here’s it’s refund policy: s2Member® » Terms » Refund Policy
