Looks the PDT verify API call to PayPal failed. Is this happening on every payment? Please be sure "Your PayPal Identity Token" is absolutely correct within your PayPal gateway. Our API usage is unchanged and uses PayPal's legacy NVP/SOAP API so there's no reason for the API call itself to fail unless that setting is wrong or there was a problem at PayPal.

Two PDT failures in August, one PDT and one IPN Invalid on the same day (different orders) in September; otherwise all notifications succeed. I notice that the Paypal 'recieve messages setting is disabled. I'm not sure what that function does, but I have now set it to active.
looking at the paypal notification hsitory I see that the two below are marked as 'Recurring payment agreement expired';presumanly this is the message that was not sent because I had the function disabled;
However, I have just 'resent' the notification that failed on 10/10/2023 which provoked this post and it arrived 'verified' (though CBSubs says 'IPN Basket non-existant'. ILooking closer, I see that this too was a recurring payment transaction. It now seems that all these failed notifications are the result of subscribers having two spearate payment profiles. one of which is going to the old website; so this problem is the result of moving a website; previously existing PayPal recurring payment profiles no longer function ... I thought I'd resolved all such accounts, but clearly there are still some lurking;
I'll mark this post as 'solved'
