Root login refused

I’m setting up a custom server and getting this error:

Mar  9 17:32:48 open-ink sshd[18403]: ROOT LOGIN REFUSED FROM 192.248.179.15 port 35706
Mar  9 17:32:48 open-ink sshd[18403]: ROOT LOGIN REFUSED FROM 192.248.179.15 port 35706 [preauth]
Mar  9 17:32:48 open-ink sshd[18403]: Received disconnect from 192.248.179.15 port 35706:11:  [preauth]
Mar  9 17:32:48 open-ink sshd[18403]: Disconnected from authenticating user root 192.248.179.15 port 35706 [preauth]

I’ve verified that the SSH key is in the authorized_keys file, and the port is open for SSH.

turns out the custom server i’m using had root ssh disabled by default. closing this.
