Issues with Netbox 4.0.6

[msmith8fti]

Upgraded Netbox to 4.0.6 from 3.7 release and now the webhook fails. Debug output below

Mon, 08 Jul 2024 16:14:22 +0000: Sending request to /api/dcim/devices/871/ Mon, 08 Jul 2024 16:14:22 +0000: NetBox API returned status: 0 Mon, 08 Jul 2024 16:14:22 +0000: Device primary IPv4 address: Mon, 08 Jul 2024 16:14:22 +0000: Device PRTG ID:

Webhook is on the same system as Netbox so connectivity is not a concern. I have also confirmed connectivity to PRTG but I don't believe we are making it that far. I have enabled the debug webhook built into Netbox and confirmed data is received.

Any ideas on what has broken from Netbox 3.7 to 4.0?
