Issues after switching from Xfinity to ATT Fiber with only Insteon devices

Configuration
1

Hello, I had configured home assistant after insteon closed down several months ago and it has been great. I am running HA on a Hyper V virtual machine and it was communicating fine until I changed my internet provider. My internal network has not changed, I am running an eero mesh system and my internal IP range is (192.168.4.x). My internal gateway did change from 10.0.0.1 to 192.168.1.254.

I’m missing simple step but I cant figure it out. I would appreciate the guidance. Thank you in advance.

You might have to provide some more information (for me). From what I see:
Network A is 192.168.4.x.
Network B (old) is 10.0.0.1
Network C (new) is 192.168.1.x
These are 3 different networks.
How did your 10.0.0.1 talk to your 192.168.4.x (before the change)?

What is the IP of the Insteon Hub? Did it change?
Try expanding your logs for Insteon to debug and restart (in configuration.yaml):

logger:
  default: error
  logs:
    homeassistant.components.insteon: debug
    pyinsteon.topics: debug
    pyinsteon.messages: debug

Then open the log and read, there could be some information there.
