How can set up GPU Coder in jetson nano at the MATLAB???

I have a question: using gpu coder to check for third-party library availability on the target... in the process of

hwobj = jetson (host address, host name, password ) at MATLAB, followed by Cannot establish a TCP/the IP to the IP.

I used PUTTY to connect SSH, but I couldn't get the wrong host name and address.

Is there anything else I need to set up? At MATLAB... What's the problem?
