communication using tcp/ip socket

I am using TCP/IP for communication. 1: I open two matlabs on the same computer, one is server, one is client, can send and receive data: 2: I run matlab to run client code in computer A, another computer B runs server code, still can be normal Send and receive data; 3: It is strange that I put the same code, the computer A as the server, the computer B as the client, can not connect properly, the computer A open communication has been busy, the client on the computer B to connect, no any Reaction. I am using the R2015b version. if u have any advice or idea,i will appreciate that.

Do I understand correctly? These setups are working:

Computer A = Server, Computer A = Client
Computer B = Server, Computer A = Client

But this fails:

Computer A = Server, Computer B = Client

Now please explain "can not connect properly" with more details. Maybe it is just a typo in the IP address? How could we guess this...
