Custom URL Host Unreachable

Having issues getting a Custom URL working with Home Assistant Webhook. The webhook works fine with curl on the network. If entered into the app and try and run test from phone it says Host Unreachable. Phone is on the same network at the laptop I’m running curl off of. Any help would be great. I use a Xbox and the poor IR functionality is making this product a expensive paper weight.

For future people. I figured this out. Home Assistant you have to enable GET seems the app hits it with GET first and if its not enable it will say unreachable.
