Question

I have a problem with these client and server codes, I keep getting the [Errno 10061] No connection could be made because the target machine actively refused it

Answer 1

the short term solution is to use the default iis host and port normally 120.0.0.1 and 80 respectively. However am still looking for a more versatile solution.
