Paho MQTT Client Fails to Reconnect After Prolonged Network Downtime

The Paho MQTT client fails to automatically reconnect after the network has been down for a prolonged period. While client.loop_start() should handle reconnections, it isn't effective in cases of long-term network disconnections.

Changing client.loop_start() to client.loop_forever(retry_first_connection=True) resolves the issue, suggesting that the client's default reconnection mechanism might not handle prolonged network outages effectively.
