Disconnection
This error message indicates that the connection to the remote host
computer has been lost. There may be problems with the configuration or
the physical setup of the network connections of either your computer or
the remote host computer.
It is also possible that the remote host computer has been rebooted,
which has disconnected your computer from the host.
Usually problems of this kind are temporary, and you can try again after
waiting for a while. If this does not help, check your local network
connections, and if necessary, contact also the system administrator of
the remote host computer.
