SSh: Access Denied, Windows 10

I'm new to Linux in general but also even newer to the Window's 10 Ubuntu subsystem. I've been trying to set up ssh and so I set up a static ip address and logged into my router and forwarded port 22 as per usual. Using my public ip, I found a site that I was able to plug that into and the site confirmed that port 22 had indeed been forwarded.

After that I followed the instructions on the link https://superuser.com/questions/1111591/how-can-i-ssh-into-bash-on-ubuntu-on-windows-10and installed openssh-server, added my username and set up my sshd_config file as such:

After setting up open ssh I tried using PuTTY to login to my server using my public IP as the address, myusername as the user and the user's password as the password and it gives me a

Access Denied

error message. I'm positive that I'm using the right password for that user name. Why am I still being denied access? If any of you can spot something amiss or maybe a step I missed, your help would be very appreciated.
