Paypal IPN Failure

My cart has been running fine but I got this today from Paypal. Anyone know what it is ?

Please check your server that handles PayPal Instant Payment Notifications (IPN). IPNs sent to the following URL(s) are failing:

http://www.personalizeddrumsticks.net/s ... d/callback

If you do not recognize this URL, you may be using a service provider that is using IPN on your behalf. Please contact your service provider with the above information. If this problem continues, IPNs may be disabled for your account.

Thank you for your prompt attention to this issue.


?

This means paypal couldn't reach the ipn callback for some reason. If you login to your paypal account and look at the IPN History you should see a HTTP status code. 200 means successful.. something else is usually bad

I don't see an http status code anywhere. There is a status for the transactions that just shows sent. But no transactions for today. I have no idea how to fix it

Would it be a problem with the Database ?

No. it's a redirect issue..
on the paypal ipn history page click the "Message details" link. The next page will show HTTP Response Code

I also got this message. How should I resolve this? Do I need to manually disable Paypal's IPN?

I have this problem too now, and it's most vexing.
Has anyone ever found a solution? I have searched all the relevant threads, all in vain...
