Currently, we are facing an issue with a push notification webhook in our QA and PRODUCTION Acumatica environments that is unable to be sent out (the same flow works in our DEV Acumatica environment).
The function of the webhook is to refresh a purchase order (PO) cache after certain events have occurred such as: PO creation, PO updating, PO deletion, and PO status changes. More specifically, we are having trouble triggering the webhook when a PO’s status is changed (e.g. from “On Hold” to “Open”).
I will attach a few screenshots of the error messages associated with the webhook below, and can upload more information if requested.

Again, the exact same webhook flow works perfectly in our DEV Acumatica environment, and I have verified that the Address used inside the Push Notification webhook is 100% working. I’ve also confirmed via https://webhookinbox.com that the webhook is able to send data in that scenario. For some reason, Acumatica is unable to send the push notification webhook to refresh our PO cache specifically.
Any help would be greatly appreciated! Thank you in advance.
