Why should this work? Have you tried connecting in this way to an sshd that
you know works?

telnet host 23
Trying 142.103.234.x...
telnet: connect to address 142.103.234.x: Connection refused
telnet: Unable to connect to remote host: Connection refused

host is a computer that accepts and is accepting ssh connection.

You just told us it was (ssh works)
