X forwarding for SSH connection

[Y-Grigoriy]

I try to perform X forwarding for SSH connection, using Windows terminal. I want to connect to remote machine with Red Hat operation system. Following the instructions and using ssh user_name@my-server I can connect to remote machine. However, when after connection I use command export DISPLAY=localhost:0.0 and xhost +local:user_name, I get the following message: xhost: unable to open display "localhost:0.0". Also I tried to use following advice: #2785 (comment), but I got the following error:

CreateProcessW failed error:2
ssh_askpass: posix_spawn: No such file or directory
Permission denied, please try again.
CreateProcessW failed error:2
ssh_askpass: posix_spawn: No such file or directory
Permission denied, please try again.
CreateProcessW failed error:2
ssh_askpass: posix_spawn: No such file or directory
user_name@my-server: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).

[process exited with code 255]

UPDATED:
This problem was solved as follows:

1. It is necessary to modify config file (C:\Users\username\ .ssh):

Host host_name
  HostName my-server 
  User user_name 
  XAuthLocation "C:/Program Files/VcXsrv/xauth.exe"
  ForwardX11 yes
  ForwardX11Trusted yes

2. Check or/and add environment variables (This Computer -> Properties -> Advanced System Settings -> Environment Variables):

DISPLAY=localhost:0.0
HOME=C:\Users\username
TMPDIR=%USERPROFILE%\AppData\Local\Temp
PATH=C:\Program Files\VcXsrv

3. Write command in cmd:
   xauth generate localhost:0.0 . trusted
4. Checking the previous command:
   xauth list
5. In settings of Windows terminal:
   "commandline": "ssh host_name",

But now I have problem with the key combination ctrl+С. It terminates ssh-connection. Could someone help me with it?

Sorry, may be you not clearly understand me. Initially, I checked ssh-connection to remote station with red hat and I don't have problem with ctrl + C. After configuration of X-forwarding (as it is written after UPDATED in my first comment) I got problem with ctrl + C. And of cause I need to use this combination at least for killing program at Linux. Thus, the question: what could have changed after configuration of X-forwarding?
Also, I don't understand your question, but I am sure that I do not use Cygwin. But I have the installed WSL on my computer.

@Y-Grigoriy Which version of ssh are you using? Does this repro in the vintage console window (cmd.exe), or does it only repro in the Windows Terminal?

[Y-Grigoriy]

@zadjii-msft, I used cmd.exe, version: OpenSSH_for_Windows_7.7p1, LibreSSL 2.6.5

[zadjii-msft]

If this repros in just a cmd.exe window, without the Terminal involved at all, then I'm betting that this is an OpenSSH issue, not a Terminal one. PowerShell/Win32-OpenSSH#1803 looks fairly related

@zadjii-msft, Should I close this issue or can we leave it open until the question on your link to be answered?

[zadjii-msft]

Lost this one in the triage queue. Yea, let's call this /dup PowerShell/Win32-OpenSSH#1803 until proven otherwise.
