This error message indicates that SSH Tectia Client cannot establish a
connection to the remote host computer. There are several reasons that
might cause this situation.
Possible reasons:
It may be that you have simply made a typing mistake, and there is
an error in the name of the remote host computer. In this case you
should also receive an error stating that the host is unknown.
Check that you have defined the correct port number for the
connection. The port can be changed on the Connection page of
the Settings dialog.
There may be problems with the configuration or physical setup of
the network connection. Verify that other network connections are
functioning.
This problem may also arise if your local system is protected by a
firewall and the firewall has not been properly configured. If you
suspect that this is the case, ask your local system administrator to
reconfigure the firewall.
There may also be a temporary problem with the remote host
computer. If this is the case, you should wait for a while and try to
connect again later. Contact the administrator of the remote host
computer for additional information.
