PayPal IPN Failing

Hi,

I'm getting an email from PayPal that I know others have received:

"Please check your server that handles PayPal Instant Payment Notifications (IPN). IPNs sent to the following URL(s) are failing:
http://www.mydomain.com/?page=gf_paypal_ipn"

None of the previous posts on this issue seem to help me.

I'm trying to troubleshoot and I just want to share a few things in case you see the problem:

1. I know the Bad Behavior plugin has caused problems for others, but I'm not using that plugin.

2. I have a different IPN URL in my PayPal account (because I set it for another plugin on another domain) but my research in the forums here tells me that's not an issue -- as long as the IPN is activated, then Gravity Forms should be able to do the rest. (right?)

3. The HTTP response code on one of the IPN history items -- which is currently "Retrying" -- is 404.

What other plugins and/or web host server settings should I look for?

Any help is appreciated.

Thanks,
Shawn

Actually, if you are running the latest version of the PayPal Add-On you will need to use our logging Add-On. If you want, send me an email to rob@rocketgenius.com and reference this post and I'll send you the logging add-on with instructions on use.

Thanks, Rob and Chris. I'll check out the post from Carl -- hadn't seen that one yet -- and I just emailed you, Rob.

I have also discovered this since my initial post:

I had set a Premise (plugin) landing page to be the home page for my site. When trying to go to the /?page=gf_paypal_ipn manually, it would re-direct me to the actual landing page URL with the /?page=gf_paypal_ipn appended to it. (example: mydomain.com/landing-page-slug/?page=gf_paypal_ipn)

When I set a "normal" page as the home page and went to the /?page=gf_paypal_ipn, then it would open the home page with /?page=gf_paypal_ipn appended to it.

Is that a slam dunk indicator of the problem? I've got the "normal" page set as my home page now to see if PayPal will successfully process the IPN.

I'll set up the logging anyway.

Thanks,
Shawn

Just reporting back on this: I got another IPN error notification from PayPal overnight -- even after deactivating the Premise landing page as the home page -- so I'm not sure if the issue still exists or if this was just a leftover from previous transactions that occurred before the change. (???) I now have the logging add-on activated, so I'll monitor that and let you know what I see. Thank you!

I got the same email "Please check your server that handles PayPal Instant Payment Notifications (IPN). IPNs sent to the following URL(s) are failing:
http://www.mydomain.com/?page=gf_paypal_ipn"

Wondering how to figure out what's going on?

I think it's working now.
