I have a function that adds credits to a users account when they purchase credits via a Gravity Forms form. This has been working fine until a transaction came in today where the payment status hasn't changed from Processing and there is no transaction information.
I enabled the logging addon and resent the IPN and get the following error
DEBUG --> Response: WP_Error Object
(
[errors] => Array
(
[http_request_failed] => Array
(
[0] => couldn't connect to host
)
)
[error_data] => Array
(
)
)
ERROR --> IPN request could not be verified by PayPal. Aborting.
Any idea what could be causing this?
