OpenTherm Gateway failed to reconnect

[DJTerentjev]

The problem

I case Gateway lost power or was disconnected from ethernet and was connected again HA failed to reconnect. Once connection was lost, got error (MainThread) [homeassistant] Error doing job: Task exception was never retrieved (None). This error appear once and no more attempts to reconnect as I can see in the log. HA doesn't reconnect to Gateway unless integration reloaded or HA restarted.

I downgrade HA to core-2024.5.1 And in case of lost connection error was: Could not connect to serial device on socket://192.168.1.12:23. Will keep trying. Reported error was: Could not open port socket://192.168.1.12:23: timed out Once Gateway back to ethernet, HA successfully reconnect to Gateway .
