ssh connect Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password)

I have a pair of keys to epadmin on machine A. I copied them on machine B in home folder of epadmin via scp in folder .ssh

command for access : ssh [email protected]

[[email protected] .ssh]$ ls -la
total 24
drwxrwxr-x 2 epadmin epadmin 4096 May 12 14:41 .
drwx------ 6 epadmin epadmin 4096 May 12 14:40 ..

Here is a piece of -vvv(Verbose) log

I can’t login without password

Piece of sshd_config. I have tried to uncomment RSAAut and paste no to password auth. There were no changes

# Authentication:
#RSAAuthentication yes
#PubkeyAuthentication yes
#AuthorizedKeysFile     .ssh/authorized_keys
#AuthorizedKeysCommand none
#AuthorizedKeysCommandRunAs nobody

# For this to work you will also need host keys in /etc/ssh/ssh_known_hosts
#RhostsRSAAuthentication no
# similar for protocol version 2
#HostbasedAuthentication no
# Change to yes if you don't trust ~/.ssh/known_hosts for
# RhostsRSAAuthentication and HostbasedAuthentication
#IgnoreUserKnownHosts no
# Don't read the user's ~/.rhosts and ~/.shosts files
# To disable tunneled clear text passwords, change to no here!
#PasswordAuthentication yes
#PermitEmptyPasswords no
PasswordAuthentication yes

# Change to no to disable s/key passwords
#ChallengeResponseAuthentication yes
ChallengeResponseAuthentication no
