Hello,

You got an error like this on Google Cloud , AWS, Azure or something like that.

the problem is about your sshd_config file. 

change the PasswordAuthentication yes from no 

 sudo vi /etc/ssh/sshd_config

PasswordAuthentication yes 

:wq!

and restart sshd service

##sudo systemctl restart sshd

thats All.
