1. Make sure you have a current version of PuTTY.: Yes, the PuTTy version is 0.7 which is the latest version.
Go to section Connection > SSH > Auth > GSSAPI and disable the option Attempt GSSAPI authentication.
: It also failed.
2. Try a ssh client other than PuTTY - for example, MobaXterm.
: I can reach other server which is on the same network with this server using PuTTy.
3. Make sure you have a current version of CentOS: Yes, it is a current version.
yum update
4. Check, if the IP that the Centos has, is not the same as another machine on the network.
: The IP is not the same as another server.
5. For Root login, edit the sshd_config file in /etc/ssh/sshd_config and then restart sshd:
..................
# Authentication:
#LoginGraceTime 2m
# If it's set to without-password then root login is allowed but only using a key, not using a password
PermitRootLogin yes
#StrictModes yes
.................
: Already edited.
6. Check the status of SELinux on your system:
sestatus
getenforce
Disable SELinux Temporarily:
setenforce 0
(enable setenforce 1)
Restart sshd service:
systemctl restart sshd
Already disabled.
