Hi Team of LWIP TCPIP Support Team,

As of now I am working with R7FA6M3AH Controller and Project is fully IOT
based and we are using MQTT to update the firmware using OTA mechanism, If we
parallelly try OTA for master firmware upgradation and ping script to know the
device info, And we are seeing that TCP Retransmission issue is generating
from server side that causes to close the tcpip communication.

Note : Before resetting the communicartion we are observing that Encrypted
alert, FIN and RST flag is setting. I have attached Wireshark logs for you :)

Thanks and Regards,
Ramesh Janagi
Embedded Design Engineer
