Problems setting up givtcp

I’m a nubie HA user. I am following the “speak to the geek you tube tutorial for givenergy local control. Setting up on a Home Assistant Green. When first loading gitcp it is not discovering my givenergy ac inverter connected to my battery. This inverter is connected to my network via WiFi dongle. I am able to see it and control it via givenergy app. Can anyone help please.
