Connection closed by foreign host.

Cause

When a user telnet(1)s to another system, this message can appear if the user takes too long to type the correct password, if the remote host cannot create a login for this user, or if the remote host goes down or terminates the connection. Data loss is possible if files were modified and not saved before the connection closed.

Action

Just try again. If the other system has gone down, wait for it to reboot first.
