Unable to access the win10 PC with OpenSSH installed through ssh command

I have installed the OpenSSH client and server in my win10 PC through this website (https://learn.microsoft.com/en-us/windows-server/administration/openssh/openssh_install_firstuse). However, when I tried to access the PC with ssh command through another PC, the ssh connection showed the error message with Permission denied, please try again. even if I entered the correct username and password. When I tried to access through administrator, the error message was Connection reset by xxx.xxx.xxx.xxx.

In order to verify this problem, I tried ssh command on the same PC. And the error message kept showing. But when I use ssh command to access another Linux PC, everything was working functionally.

Are there any other settings that need to be done with the OpenSSH server?

My OS is win10 Enterprise Edition LTSC ver. 1809 with 17763.1457

    Ensure you set static IP address and ensure /etc/ssh/sshd_config file:
    To enable password authentication, uncomment

    PasswordAuthentication yes

    To enable root login, uncomment

    PermitRootLogin yes

    To enable SSH key login, uncomment

    PubkeyAuthentication yes

    AuthorizedKeysFile .ssh/authorized_keys

    I have the same issue. Spending a lot of time installing and configure the OpenSSH server on Windows 10 and tried to access it via MacOs OpenSSH client, but nothing was resolved. All these problems with Windows 10, but Linux and MacOs OpenSSH servers are running without any problems. Why this problem ?
