Hi Guys,

I’m hoping someone can provide me with some info on how to fix this problem. We have espresso set up on our site and its working fine or at least was. We had some problems with IPN in the past which would stop working and then start again but it seemed to be fine after I did updates and checked all the IPN settings. Everything worked fine until the 08 March when IPN stopped working with no changes made to it. I am getting emails from paypal that IPN messages are not getting through and now paypal have disabled the IPN until the issue is fixed which is less than desirable as you might imagine.

There does not seem to be any pattern to the failures. A batch of them will fail in a row and then out of the blue some paypal IPN re-tries will succeed. The failure messages all look like the following:

[03/14/2013 9:11 AM] – Errors from IPN Validation:

Success Setting host: https://www.paypal.com/cgi-bin/webscr
