I have a device that is sending data to my server every minute. (No DNS is runnig). when I start my device, I am getting a warning message.
[Warning] IP address '192.168.xx.xxx' could not be resolved: the host is not known.
then every minute I am getting following warning in my mysql log file. (of course new connection number every minute. this is one sample)
2019-05-15 11:12:00 840 [Warning] Aborted connection 840 to db: 'unconnected' user: 'root' host: '192.168.xx.xx' (Got an error reading communication packets).
Eventhough there is this warning, But my device is still posting data into mysql server every minute.
I don't know why this warning says db: 'unconnected'? Any suggestions. (I am using static IPs)
