Hello,
I facing issue while login to server via SSH.

Hi Woo-joo.
It looks to me like this is simply a case of your login information to connect to that server being incorrect and thus denying you access. Make sure that you have the correct username and password. If you have any more issues, please, don't hesitate to contact us again with more information so we can look into it in more detail.
Thank you.
