[lwip-users] netconn_connect function returns error '-5'

[address@hidden]

Hi,

I am working on the code which connects to a simple server,but when I use netconn_connect function to connect  with the server,netconn_connect function returns '-5' value that is 'ERR_ABRT'.

I am using LWIP 1.3.2 on FreeRTOS .

For debugging, I'm printing debug information,my device keeps re-transmitting SYN three times.That is client sends an SYN,but the 

server doesn't send back ACK-SYN.

To be honest I am not getting the idea with the netconn_connect () callback,What should I look at? Am I doing something wrong?
