Answer 1

In your sshd_config did you identify the users who are allowed to connect?

# Authentication:  
Allowusers testuser  

Answer 2

i just ran some tests and that Pubkey statement is not the problem. I was not able to login with my admin account, so I had to comment out the AllowUsers because it was only letting my testuser in.

Add these 2 lines to your config.

SyslogFacility LOCAL0
LogLevel Debug1

Then recycle the sshd service and try to log in again. Check for errors in the C:\ProgramData\ssh\logs\sshd.log file.

Here is my sshd_config file. (Update; I used Filezilla and connected via SFTP.)

# This is the sshd server system-wide configuration file.  See  
# sshd_config(5) for more information.  
  
# The strategy used for options in the default sshd_config shipped with  
# OpenSSH is to specify options with their default value where  
# possible, but leave them commented.  Uncommented options override the  
# default value.

Answer 3

even I am sure that password I am using is correct

Check the Security eventlog for logon errors.

Check the OpenSSH server logs for errors.

Answer 4

Before trying to use scp, try logging on to the remote machine using ssh. If ssh doesn't work there's is no hope of scp succeeding.

Are the machines in a workgroup or a domain?
