Paypal Instant Notifications Warning

I keep getting this emails from PayPal saying "Please check your server that handles PayPal Instant Payment Notifications (IPN). IPNs sent to the following URL(s) are failing:

The link is below, and when I click it shows up as invalid in the browser.

How can I fix that?

Thanks,

PayPal Standard, Advanced, or Pro? We've 3 PayPal gateways please be sure to be specific. IPN URLs can't be accessed directly as they process POST data so navigating to the URL will error as expected.

I know I must have some wrong setup, or maybe PayPal changed something. I did that setup a long time ago, I think it is the standard, because in the gateway type it just say standard.

Thanks,

Do you have any IPNs logged within CBSubs > Notifications? If so are they showing as failed? If they are check within CBSubs > History Log to see what the error is that they're failing with. My guess is it's probably a validation issue and suggest checking to be sure you've set the following all correctly.

PayPal Business (email or secure merchant ID): Suggest Merchant ID here otherwise use the email address marked as PRIMARY in your PayPal account

PayPal Main receiver account (email) (if Business is different from your main account): This should be the email address marked as PRIMARY in your PayPal account

Your PayPal Identity Token: Ensure you copied this from your PayPal account completely as sometimes double-clicking the input to select its value at PayPal only selects up to a hard break like a dash or underscore.

The PayPal API credentials are optional, but I recommend also setting them.

Thank you for the info!
I did the setup again, added the merchant ID and email, I re-entered the api credentials and password,
I've also re-activated the Instant Notifications on PayPal and so far I had I did not get any new warnings.
I'll keep my fingers crossed!


Thanks again,

I'm still getting the PayPal notifications errors. Also, is not all of them, some notifications go through just fine and some others have a warning.

I'm out of ideas. Do those errors affect the payments in any way?
Are these notifications really necessary? Can I just turn them off from PayPal?
