IPN from Paypal is failing

[sittbrunnen]

I am trying to set up Paypal but after some tests I got this message from them. IPN sent to adress below are failing:

https://sittbrunnen.se/index.php?option ... =component

Do you have any idea what to do? They might deactivate IPN to my account, if I not fix it.

Hi, did you ask them what this exactly mean?
