Hey @SledgeSRV out of curiosity, if you change homeassistant.local:8123 to just the IP address of your homeassistant does it work? My immediate thought here is that the device you are trying to send the command from can not resolve homeassistant.local. I have not actually tried to use an action file yet to trigger a scene but will give some further testing of this soon. Can you also check the kodi log to see if is giving any response such as unable to resolve or connect?
