SSH permission denied publickey

Generated public and private key with
`# ssh-keygen`
Add it to my server with
`# ssh-copy-id -i /root/.ssh/id_rsa raspberrypi4`

Trying to connect with
`# ssh -i /root/.ssh/id_rsa -p 22412 nae
vus@raspberrypi4`
returns me
`naevus@raspberrypi4: Permission denied (publickey).`

The report names no source file or test. Start by reproducing the SSH login with the stated ssh-keygen, ssh-copy-id, and ssh commands, including the shown key path, username, host, and port; done means determining why public-key authentication is rejected and correcting the reported behavior.
