About a week ago (around the same time I upgraded to the latest version of Gravity Forms), I started getting these messages from PayPal that IPN would be disabled if I didn't fix this issue. I'm not sure how to fix the issue, as I didn't make any changes to my website or the configuration.
Can anyone help?

Please check your server that handles PayPal Instant Payment Notification (IPN) messages. Messages sent to the following URL(s) are not being received:

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.
Once you or your service provider fix this problem, you or your service provider can resend the failed messages from the IPN History page. If this problem continues, PayPal may disable the IPN feature for your account.
Thank you for your prompt attention to this issue.
Thanks,
