    Default Paypal IPN updates require intervention?

    site: https://www.proteawines.jp/shop/
    OS: Debian 11.0 (64-bit)
    Zencart: 1.5.6c with customizations for Japanese language
    DB: MariaDB 10.3.24
    PHP (with nginx/php-fpm): 7.3.15-3

    Paypal send notifications of updates to IPN IP addresses in December 2020, which I ignored since I have no restrictions in my route, OS firewall or nginx web server configuration for HTTPS traffic.

    Paypal has been working for transactions, last one was yesterday 22nd May (I could capture the payment successfully in ZenCart, and it is listed in my PayPal account correctly as "pending").

    That said, the morning I received a message from Paypal stating that there are IPN errors, and that IPN may be stopped if this continues.

    Dear Gernot Hassenpflug,

    Please check your server that handles PayPal Instant Payment Notifications (IPN). IPNs sent to the following URL(s) are failing:

    https://www.proteawines.jp/shop/ipn_main_handler.php

    If you do not recognize this URL, you may be using a service provider that is using IPN on your behalf. Please contact your service provider with the above information. If this problem continues, IPNs may be disabled for your account.

    Thank you for your prompt attention to this issue.

    PROTECT YOUR PASSWORD

    NEVER give your password to anyone, including PayPal employees. Protect yourself against fraudulent websites by opening a new web browser (e.g. Internet Explorer or Firefox) and typing in the PayPal URL every time you log in to your account.

    PayPal Pte. Ltd. is a Singaporean company registered with the Financial Services Agency of Japan as a (1) Funds Transfer Business Operator with Registration No. 00026 issued by the Director-General of the Kanto Local Finance Bureau and (2) Third Party-type Issuer of Prepaid Payment Instruments with Registration No. 00705 issued by the Director-General of the Kanto Local Finance Bureau.

    PayPal RT000111:en_US(en-JP):1.0.0:a5c4c469241f6
    I checked as best I could the Paypal module code, there is no explicit listings of IP addresses.
    In the ZenCart error logs there are errors of this form:

    [23-May-2021 12:39:49 Asia/Tokyo] Request URI: /shop/ipn_main_handler.php, IP address: 173.0.81.65

    (DB values replaced by asterisks, paths snipped)

    Not sure if there is anything I need to do regarding IPN IP addresses, or whether the error is caused by, say, strict mode in the DB?

    Any comments appreciated.

    @gernot, do you, by any chance, have the PayPal debug-to-file enabled? That would (have) gathered some of the information needed to further understand the source of the error.

    Hello @lat9,
    Thank you for your response. I had not, but I have enabled it now.
    I notice in my logs I have these kinds of errors from October 4th 2020, so I assume they are not directly related to the IP address changes rolled out in December.
    I hope I will see something in the extra logs today, or whenever Paypal initiates some kind of checking.

    Hi @lat9,
    After activating "log to file" I got a more extensive error log:

    Probably fixable by applying the v1.5.7 changes shown here: https://github.com/zencart/zencart/c...cf09751b4cd003
    to the functions_paypal.php file.

    DrByte,
    Many thanks, I had been following backported fixes but missed this one. Applied it now, will see what happens after I make an update to the Paypal order shortly.

    Default Re: Paypal IPN updates require intervention?

    Hmm, not sure why but I am still getting a daily error message from Paypal (see initial post).
    I did have one more ipn_*.log, but it contained no POST data and said that the exchange looked browser-initiated (when I restored a session maybe) rather than from Paypal.
    Nothing in my error logs that I can tell though. I guess I should look at my web server logs next, but I do not have any blocking on HTTP or HTTPS ports.
    Any other options I should consider?

    Since there was a MySQL error created initially, the on-site PayPal processing didn't complete its handshake with PayPal. That's why the PayPal message was originally correct ... there was an issue with the IPN post-back address.

    Now that you've added that (int) cast, the IPN sequences will finish successfully and PayPal will note that with each IPN request.
