SSH login public key denied
Hello everyone, it's my first time working with Digital Ocean. I've already created my droplet with ubuntu 16, created my SSH keys on Mac and included in the droplet. But I can't login using SSH without including the private key path:
ssh root@DROPLET_IP -i /path/to/private_key
If the path to private key is included I can log in, otherwise the public key is denied.
Can anyone help me?
