Can’t connect NR to control Kodi?

General

As I continue to try things, I can get the following to work directly into a browser.

http://192.168.1.227:8189/jsonrpc?request={"jsonrpc":"2.0","id":"1","method":"GUI.ShowNotification","params":{"title":"Test Household","message":"Everything is great","displaytime":6000}}

Which seems to confirm the ip and port were correct within the other attempts, but no idea why I cant send these jsonrpcs directly via node Red
