I’m getting a warning email from PayPal after every transaction. The transaction goes through as does the funds transfer. This suddenly began in the last 10 days. What may be done to sort this out?

Thank you.

Hi ######,

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

www.######.co.uk

If you don’t recognise 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 helping resolve this issue.
