It was working before but now somehow its not working.

ssh root@ gives below error message
Permission denied (publickey).

While for other user its working ( i.e ssh myUser@ )

I had tried many tutorials on digital oceans and from stackoverflow, but none working and I can't login with root.

Anybody has resolution?

Add your public key to /root/.ssh/authorized_keys.

This happens if you have multiple SSH keys loaded into your agent.

Lets say your key file is idrsa and respectivly

ssh -i ~/.ssh/id_rsa root@

If you don't want to type the -i aspect each time create a file in your .ssh folder named config and add an entry like below

Host whatever_name
    HostName or
    User root
    PreferredAuthentications publickey
    IdentityFile /path/to/.ssh/key_file
    UseKeychain yes
    AddKeysToAgent yes

update the entry to match your setup.
