Ok, time to start some serious debugging:
Where could the error be?
a) your PC - we are simply not qualified to help you there, please refer to the PC part of the forum
b) the server you try to contact
b1) ssh communication is somehow not possible:
Try to log in to the host in question with ssh. Install some ssh (putty for example) on a pc and use it to connect to the server. If you get to a login prompt asking for user name and password everything is ok.
b2) communication is not possible because of wrong user credentials
I saw on your picture you can change the port and the means of communication. Uncheck ssh and change the port to 20 (which is telnet - you said you can reach the host via telnet) and try again. Does the error go away this way?
b3) root user is not allowed to log in
It is a common security measure to disallow the root user to log in from outside. (users have to log in with their personal account and then switch to root.) I see from your picture that you use the root user. Try to log in using putty (or any other securified terminal emulator) as root user with the same password you used in the screen. If you can log in this way you have proven that this is not the problem.
Ok, so far my ideas. I hope they help.

ssh-keysign
ssh-keysign(1M) ssh-keysign(1M)
NAME
ssh-keysign - ssh helper program for host-based authentication
SYNOPSIS
ssh-keysign
ssh-keysign is used by ssh(1) to access the local host keys and generate the digital signature required during host-based authentication
with SSH protocol version 2. This signature is of data that includes, among other items, the name of the client host and the name of the
client user.
ssh-keysign is disabled by default and can be enabled only in the global client configuration file /etc/ssh/ssh_config by setting Host-
basedAuthentication to yes.
ssh-keysign is not intended to be invoked by the user, but from ssh. See ssh(1) and sshd(1M) for more information about host-based authen-
tication.
/etc/ssh/ssh_config
Controls whether ssh-keysign is enabled.
/etc/ssh/ssh_host_dsa_key
/etc/ssh/ssh_host_rsa_key
These files contain the private parts of the host keys used to generate the digital signature. They should be owned by root, readable
only by root, and not accessible to others. Because they are readable only by root, ssh-keysign must be set-uid root if host-based
authentication is used.
ssh-keysign will not sign host-based authentication data under the following conditions:
o If the HostbasedAuthentication client configuration parameter is not set to yes in /etc/ssh/ssh_config. This setting cannot be overri-
den in users' ~/.ssh/ssh_config files.
o If the client hostname and username in /etc/ssh/ssh_config do not match the canonical hostname of the client where ssh-keysign is
invoked and the name of the user invoking ssh-keysign.
In spite of ssh-keysign's restrictions on the contents of the host-based authentication data, there remains the ability of users to use it
as an avenue for obtaining the client's private host keys. For this reason host-based authentication is turned off by default.
