MQX rtcs client TCP connect return 5705

Hi I am trying to create application with TCP client in a TWR - K60n12 using MQX.

I have a problem with connection. Function  connect(....) return :5705. I guess it is timeout because it takes long time...

Do you know what doest it mean (5705)?

Could you please look into code if I made a error in code?

Is it necessary to modify HW jumper on the TWR kit?

I have a C# (server) application which is waiting on specific port (60000) to connection (from TWR K60n12).

I am using static IP address TWR  PC:


Thank you very much for your HELP. I have spent long days on this problem.
