Lost connection to inverter after changing settings multiple times in quick succession, needs HA restart

[canton7]

From https://github.com/nathanmarlor/foxess_modbus/discussions/40#discussioncomment-5720147:

The only issue was the one I mentioned with going in/out of the config repeatedly to change poll settings - after 3 or 4 times in short succession it goes into error (see below), I tried deleting the integration and adding again but it failed as it couldn't access the IP address - it needed an HA restart to resolve.

These were the logs when it lost it:-
