Update IP Address for Insteon Hub

My Insteon Hub was left with the ethernet unplugged overnight and now says in HA “Failed setup, will retry” and I assume the IP address of the hub is different. The obvious fix is to update the IP for the Insteon integration in HA but it appears there’s no way to do that. The instructions say to “add device” in the integrations > configure, but all the devices are already there and I don’t want duplicates or zombie devices. I’m also noticing I cannot see the old Insteon IP in HA so I cannot even verify this is the issue. What’s the best way to get an existing Insteon configuration running again when the problem is as simple as temporarily disconnected ethernet?
