We recommend you use 'terminal based SSH authentication' to avoid this issue.

Password not accepted. What is the reason?

Well managed servers usually do not allow root login.

You can change the option in sshd_config. It is usually located in /etc/ssh directory.

PermitRootLogin no => PermitRootLogin yes

A restart of your sshd daemon is required.

I try dialog and terminal.
Password not accepted.

This may be because there are special characters in your password. We've corrected this issue in the latest build of Xshell, so if you have not updated, please do so and try again.
