I opened, entered server IP and root password, pushed Start and the error occurred:

Error code #1001: Unable to connect. No matching comp found: client zlib server none,


Such error occurs if compression is not enabled in your OpenSSH server.


Enable compression in SSH by adding or uncommenting the "Compression yes" line the /etc/ssh/sshd_config file. Restart sshd after the configuration files modification.
