Did you try "ssh -o PreferredAuthentications=password user@ip"?
Somewhere in your config (or by default), public key is set as the
preferred method of authentication. You may have max retrys set to one,
which would cause a disconnect because after the public key is denied
you have used your one authentication try.
To fix the problem, try one of the following:
Set preferred authentication method to password.
*Increase max authentication trys. (probably easiest)*
Use syntax: "ssh -o PreferredAuthentications=password user@ip" for every
login.
I hope this helps!

I'm trying to re-establish SSH communication between two of my hosts. I
can use SSH to login between the hosts as a normal user, but not as the
root user. Root logons between the hosts used to work, but I may have
screwed up and regenerated the keys. PermitRootLogin is set to 'yes' on
the remote host. When I have no /root/.ssh/id_rsa file, I can log into
the remote host as root with my root password. However, when I
regenerate the id_rsa key, in preparation to sending it to the other
host, I get these lines in 'ssh -v:'

I don't understand why it's trying the publickey method.
On the remote host, I've removed the lines in /root/.ssh/authorized keys
for the host I'm coming from, and restarted sshd,
I'm at a loss. I suspect that this is an easy problem for someone who
knows SSH better than I do, and I'm hoping you all can help me. Thanks
in advance for your advice and suggestions.
