Speculating now; but perhaps you are not using the correct version of the software

when using ch>>>l getting the following error client: server: Remote R:8888=>8888 cannot listen

Is your server running?

Other troubleshooting would be to try and s*h to yourself and see if you can establish a connection.
If not then you need to configure your box (kali) to accept connection.
