You might have been locked out of the server by the protection in place to avoid bruteforce logins. See the end of the page “ssh and security” : https://yunohost.org/#/ssh
Then try to use a password first and then later “ssh key”. Which user do you connect as ?
I setup the server and everything setup in Yunohost admin panel.
Now i wanted to login to root in console via Bitvise ( a software like putty) now it wont let me in it ask me for password. I am trying to login as root user.
As said, root login is no longuer active, you should use admin now.
If you have to login with root, you have to edit /etc/ssh/sshd.config in order to add PermitRootLogin yes and restart ssh with service ssh restart.
Hope it could help you.
Yes : admin with the password define during the installation.
On the web admin’s portal https://your_server/yunohost/admin, it’s the same password.
With ssh :
ssh admin@IP
or if you have change the common port 22
ssh admin@IP -p port_number
Then you had to use sudo to run some commands.
