Password Authentication only denied OpenSS? - windows

Question

Specifically to only using PasswordAuthentication to make a connection. I know there are many posts with regards to public key permission denied. With remote SSH connection attempt:
sshd PC UserName#staticIP : Permission denied (publickey,
keyboard-interactive)
root#staticIP : Permission denied (publickey,
keyboard-interactive)
I have a windows PC behind a (public) router which has a static IP assigned to it. For now I just want to get an initial ssh connection before moving to key authentication. I am not getting a password prompt:
Settings sshd_config:
PermitRootLogin yes
PubkeyAuthentication no
PasswordAuthentication yes
Logging yes
LogLevel VERBOSE
On the public router with static IP:
SSH and port 22 is allowed on my router, inbound and outbound.
I get no log message in my router's Firewall Log when trying to ssh in.
I have port forwarding on, for port 22 to the PC where I have the
sshd running.
sshd PC: Firewall has inbound rule allowed for port 22 SSH. The "Allow apps to communicate through Windows Defender Firewall" is allso allowed on Private and Public for both OpenSSH Server and OpenSSH SSH Server.
HrPing is successful: hrping staticIP -p 22 -n 4 -l 1000
Using PowerShell as administrator as well as from an Ubuntu PC I have tried:
ssh sshd PC UserName#staticIP -p 22
ssh root#staticIP -p 22
On the sshd/Server PC > Services > OpenSSH SSH Server > Log On: should that be selected as Local System Account or This account - and the you select a user?
In ProgramData > SSH > Logs:
10952 2022-06-15 16:36:18.724 Connection from 102.250.4.93 port 12692 on <Local LAN IP address sshd PC> port 22
10952 2022-06-15 16:36:18.987 Connection reset by authenticating user <UserName> 102.250.4.93 port 12692 [preauth]
I get no messages in windows eventViewer under OpenSSH. There are no key's at either the client or sshd PC. With the initial connection attempt, the sshd PC's fingerprint is copied over to the client's known_hosts folder, but that also ends in permission denied.

Answer 1

You can see from the debug output
debug1: Authentications that can continue: publickey,keyboard-interactive
and from the final error message
Permission denied (publickey, keyboard-interactive)
That the server is not accepting password authentication method (otherwise the word password would've been included in the list).
If you have set PasswordAuthentication to yes by yourself then make sure to restart the ssh service in order for the changes to take effect.
