PayPal IPN Fatal Error on your Site

[localzuk]

So, we recently decided to switch from Google Checkout to Paypal due to us wanting a VT (when we get PayPal Pro etc...).

We have it working in so much as people's money is taken, but it does not update the status of the order to 'Confirmed' once the money is there.

Instead, we get an email as below:

A fatal error occured while processing a paypal transaction.

What have I missed?

Nobody? This is an issue, as our email inbox is currently being spammed with these error messages...

[localzuk]

Has no-one else had this issue?

[localzuk]

Ok, I've figured out what the issue will be. We have a proxy server between our web server and the internet - all traffic on our network has to via it. The notify script does not do this, it tries to connect to paypal.com directly.

Does anyone have a way of getting it to send data via our proxy? We can't alter the fact it has to go out via the proxy.

I am currently having the same problem. Did you ever find a solution?

G'day,

The simplest solution would be to change the firewall to allow out bound connections from you web servers IP address.

I assume it is a business, reason you need to use a proxy, usually for web filtering.
Since this is a server it does not need to be proxied and you have a sound business reason for the data to not go via the proxy.

What proxy and why do you need to use one, out of interest?
