Integration crashing Home Assistant when Reloading device that is down

[irvintim]

I just upgraded HA to 2025.2.5. The Hubitat integration version is 0.9.43.

I have 4 Hubitats configured with the integration. The configuration uses a different server port for each.

These are the ports:
tcp 0 0 10.26.10.11:18125 0.0.0.0:* LISTEN
tcp 0 0 10.26.10.11:18124 0.0.0.0:* LISTEN
tcp 0 0 10.26.10.11:18126 0.0.0.0:* LISTEN
tcp 0 0 10.26.10.11:18123 0.0.0.0:* LISTEN

One of the Hubitats is down when Home Assistant reboots, and so it is not configured correctly by the Hubutat integration (as you would expect).

The above exception was the direct cause of the following exception:

During handling of the above exception, another exception occurred:

    raise ConnectionError(str(e))

However, it seems that it gets part of the way configured and is listening on the port for the device to connect.

So, then if I click on the "Reload" button in the service for the configured Hubitat device, Home Assistant crashes and I need to manually restart it (or reboot):
