Server refused our key - Centos 7
I generated rsa key-pair, Using puttygen.exe running on windows, I imported the private key and tried to use it to login to a CentOS Linux release 7.5.1804 (Core) (running on VirtualBox) and it gives the following error: "server refused our key".
I tried to search for solution and some of the recommendations were to chmod of .ssh directory to 700 while authorized_keys is set at 600. I wish to say that I actually created the authorized_keys directory under .ssh directory.
I also generated rsa keys with puttygen.exe and copied the public key to my linux machine and tested, but the error remains.
Please could anyone offer some assistance.
Thanks in advance.

Thanks all; got it figured out. The problem was creating a directory instead of a file.
I wish to say that I actually created the authorized_keys directory under .ssh directory.
Thanks all once more.

ssh-copy-id
SSH-COPY-ID(1) General Commands Manual SSH-COPY-ID(1)
NAME
ssh-copy-id - install your public key in a remote machine's authorized_keys
SYNOPSIS
ssh-copy-id [-i [identity_file]] [user@]machine
DESCRIPTION
ssh-copy-id is a script that uses ssh to log into a remote machine (presumably using a login password, so password authentication should be
enabled, unless you've done some clever use of multiple identities)
It also changes the permissions of the remote user's home, ~/.ssh, and ~/.ssh/authorized_keys to remove group writability (which would oth-
erwise prevent you from logging in, if the remote sshd has StrictModes set in its configuration).
If the -i option is given then the identity file (defaults to ~/.ssh/id_rsa.pub) is used, regardless of whether there are any keys in your
ssh-agent. Otherwise, if this:
ssh-add -L
provides any output, it uses that in preference to the identity file.
If the -i option is used, or the ssh-add produced no output, then it uses the contents of the identity file. Once it has one or more fin-
gerprints (by whatever means) it uses ssh to append them to ~/.ssh/authorized_keys on the remote machine (creating the file, and directory,
if necessary)
