 Issue :

Permission denied, please try again.
Permission denied, please try again.
username@194.233.123.65: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).

Soltion :

this message caused public key and private key is not match now this is the solution

on your client computer

type 

ssh-keygen -t rsa -b 4096

this code will generate two files on directory ~/.ssh/

id_rsa and id_rsa.pub

now we will copy the public id_rsa to the server now you can type 

ssh-copy-id server_user@server_ip

code above will copy content of id_rsa.pub to ~/.ssh/authorized_keys on server 

and now Your can remote your server withour password

like this 

username@194.233.123.65

[username@vmi828895 ~]$
