The server connects and communicates normally, and the Client experiences a return value = -13, Abort in the connect function.
Using the Netconn API, the user program is hercles_3-2-8.exe. PC IP is 192.168.0.223 and Device IP is 192.168.0.222.
The code below is the Client connection code, which connects to TCP/IP and sends every second.
osThreadDef(TCP_Task, TCP_Task_Func, osPriorityBelowNormal, 0, 512);
TCP_TaskHandle = osThreadCreate(osThread(TCP_Task), NULL);
void TCP_Task_Func(void const * argument)
{
/* init code for LWIP */
MX_LWIP_Init();
/* USER CODE BEGIN 5 */
osDelay(1000);
const char* message = "Hello message!\n\r";
ip_addr_t PC_IPADDR;
IP_ADDR4(&PC_IPADDR, 192, 168, 0, 223);
ip_addr_t Device_IPADDR;
IP_ADDR4(&Device_IPADDR, 192, 168, 0, 222);
struct netconn *conn;
err_t err;
conn = netconn_new(NETCONN_TCP);
err = netconn_bind(conn, &Device_IPADDR, 55151); // return Value = 0
err = netconn_connect(conn, &PC_IPADDR, 55151); // return Value = -13(Abort)
osDelay(100);
/* Infinite loop */
for(;;)
{
netconn_write(conn, message, 17, NETCONN_NOFLAG); // return Value = 0;
osDelay(1000);
}
/* USER CODE END 5 */
}

I tried UDP like the link above, and UDP didn't work either.(Once the PC side sends data, the Device will continue to send data thereafter.)
