TM4C1294NCPDT: TCP Connection not established when LAN cable reconnected

Part Number: TM4C1294NCPDT
Other Parts Discussed in Thread: SYSBIOS

Hi,

We are using TM4C1294NCPDT TCP using RTOS, Please find the attached source code for your kind reference.

When the LAN cable is connected system is functioning as per requirements.

When ever the LAN cable disconnected and reconnected system is not getting connected to server until we power restart the device.

We are using two different tasks to connect different ports as (5000 and 5001).

Other than this issue system is working fine.

Can you guide us how to fix this issue on priority basis.
