Basic webhook call doesn't work from HE

[slip1n1fall]

I have a local (only) camera NVR, which has a webhook interface to trigger various actions. It provides a URL in the below format. Calling this URL properly triggers my NVR from a PC web browser. However a GET from HE RM5 doesn't. Before I go down the rabbit hole and break out the network tap+wireshark, can anyone offer some suggestions? All devices, NVR, HE, and test PC are on the same subnet. All devices assigned static IPs. No switch/routing rules or policies are associated with any of the devices.

Is it the port 5000 that's throwing this?

I'm totally new to webhooks (this is my first) so I may be overlooking something simple.
