I generated a ssh key pair with ssh-keygen, use ssh-copy-id to the server and checked that the public key was added to authorized_keys, but then when i try to connect with ssh -i ~/.ssh/MY_KEY user@server it is still asking me for the password. I don't have root privileges in the server but my .ssh directory only has "authorized_keys" and "known_hosts" files, both have the public key "MY_KEY". I already checked every permission on /User, /.ssh and both files inside /.ssh but i don't have access to sshd_config
This is what i get when trying to connect with
ssh -v -i ~/.ssh/MY_KEY user@serverIP

I honestly don't know what else to try. I don't get why is it trying the correct key (MY_KEY) but it clearly fails.
