Hi, so i use my domain to recive POST requests from PayPal. It worked all fine untill it just stopped working. When i run the code on my pc it all runs fine but on my server it fails (it doesnt give me any info only that it didnt work on paypal. What do i do?

What steps have you taken to resolve the issue?

I have tried checking out my server (no errors)

Ran code via my pc (and via ngrok domain) (no errors and worked)

Where exactly are you seeing this sparse information, that is only saying that “it didn't work”?

Can you perhaps share a screenshot of that?

Alone with the sparse information given above, it’s hard to say.

  1. Do you see anything on the “IPN History” on PayPal’s side?
    → https://www.paypal.com/merchantnotification/ipn/history

  2. Under “Firewall Events” in Cloudflare, … do you see anything around the timestamps of when you supposedly should have received these POST requests from PayPal?
    → https://dash.cloudflare.com/?to=/:account/:zone/security/events

There is a chance that your current Cloudflare WAF settings are locking PayPal out, such as e.g. if you have enabled Bot Fight Mode or Under Attack mode, for example during an apparent attack towards your website.

However, -

Chances are also that nothing may be wrong, but that PayPal simply are having (temporary) issues on their side.

If PayPal is actually making attempts to send out the notifications, I would suggest to gather further information from PayPal, such as what exactly that they see from their end (including any error code(s)/message(s) they may see).

I’ve personally experienced such PayPal notifications being delayed by an hour (or more), on several occasions.

Well that’s the problem, it doesn’t tell me anything. Paypal just says it failed, no error code no nothing. In my code i also don’t get a error or somethin. But when I try the exact same code in my pc + ngrok domain it works fine. And a few days ago it just worked as it should work. It just stopped working.

In that case, you will need to contact PayPal and request that they supply you with more detailed error information, about the failing requests.

Neither the Cloudflare Community, nor any other communities for that matter, will ever be able to dig further in to the issue, without getting a lot more detailed information.
