Paypal Sandbox not working

Hi guys,

I have been fiddling with a paypal IPN script for countless days trying to return it to its working state in which i once had it. In desperation i downloaded their example script and for some reason, not even that is working.

when i try responding to the sandbox (sandbox.paypal.com) server i get an HTTP error. But when i connect to there normal server (paypal.com) i get a validation error… which is to be expected…

So… is the sandbox server down ??? or is my script acting up ? Can anyone else VALIDATE from the sandbox server?

Thanks for the replies…
