This message is typically informational rather than an error, suggesting that the connection was lost and has been successfully re-established.
  Cause:
  
  Network Issues: Temporary network disruptions can cause the MQTT client to lose its connection to the broker.

  Solution:
  
  Check Network Stability: Ensure that the network connection between the MQTT client and broker is stable and reliable.
  Review Broker Settings: Check the configuration of the MQTT broker for any settings that might cause disconnections, such as timeouts or limits on the number of connections.
