Can't reconnect to AMI

[TECH7Fox]

Hi, I'm trying to reconnect on a shutdown event. But when Asterisk is back and it does reconnect, it fails with a RuntimeError: threads can only be started once.

Here is my shutdown event:

def handle_shutdown(event, manager, hass, entry):
    _LOGGER.error("Asterisk shutting down.")

    manager.close()

    host = entry.data[CONF_HOST]
    port = entry.data[CONF_PORT]
    username = entry.data[CONF_USERNAME]
    password = entry.data[CONF_PASSWORD]

    while True:
        sleep(30)
        try:
            manager.connect(host, port)
            manager.login(username, password)
            _LOGGER.info("Succesfully reconnected.")
            break
        except asterisk.manager.ManagerException as exception:
            _LOGGER.error("Error reconnecting to Asterisk: %s", exception.args[1])

Would be great to get this to work for a Asterisk integration for Home Assistant.
