After login SSH then paste the command on your terminal
[root@dinisoft]# netstat -tulnp | grep ssh
There was showing
0.0.0.0:22
You may try second command
[root@dinisoft]# nano /etc/ssh/sshd_config
Now opened text editor on your command line screen, you should find port number 22
Just replace port number from 22 to [different any number & delete # character front on the line. ]
then restart SSHD
[root@dinisoft]# systemctl restart sshd
now try again on the first command before exit for confirmation.
