How to resolve "The authenticity of host" message

[fun_9990]

Dear supporters, what is my problem exactly?

When I want to connect to my Linux ( subsystem on Windows 10 ) like Kali and Ubuntu and Debian

I see this error message:

The authenticity of host 192.168.1.6:4003 can’t be established. The certificate fingerprint is: SHA256 90 1D 28 46 0B 57 1A 2A B8 BA 19 3C 83 22 F6 37 CB DE 35 DF A1 BC B9 26 32 A0 A1 FC AF F5 E4 F3. Are you sure you want to continue connecting?

The session negotiation failed.

Error: Cannot create a new display, please contact your system administrator

 

my nxPort for Debian is 4001 and it is 4002 for Ubuntu and 4003 for Kali
my IP Address is localhost or 127.0.0.1

I was connected with this IP Address to my xRDP console

root@win:~# /etc/init.d/nxserver start
Starting NoMachine.
root@win:~# /etc/init.d/nxserver status
NoMachine is running (with PID: 143).

Meanwhile, when I would like go to the next step, I see this error message:

Could not connect to the server. Error is 107: Connection refused

I need NoMachine for my work

Please help me to solve this problem
