It can also change if you did network restructuring specifically you changed the route from A to B somehow, As jgt said this one is a no-brainer. Get rid of the one line of hex characters in the known_hosts. It will automatically be recreated correctly the first time you connect to the remote host.

Name
       tftp - trivial file transfer program

Syntax
       tftp [host] [port]

Description
       The  command  provides  the  user interface to the Internet standard Trivial File Transfer Protocol.  The program allows a user to transfer
       files to and from a remote network site.  The remote host can be specified on the command line.	If you specify the remote host on the com-
       mand line uses host as the default host for future transfers.

       If  a  port is specified, uses that port number instead of the standard service port.  When the user invokes the program enters its command
       interpreter and awaits instructions.  The prompt tftp> is displayed on the screen.

       The following commands are recognized by

       ?		   Displays a help message that gives a brief summary of the commands.

       ascii		   Specifies mode ascii.

       binary		   Specifies mode binary.

       connect host-name [ port ]
			   Sets the host and, optionally, sets port for transfers.  Note that the TFTP	protocol  does	not  maintain  connections
			   between transfers.  Because merely remembers what host should be used for transfers instead of actually creating a con-
			   nection, it is not necessary to use the command.  The remote host can be specified as part of the or commands.

       get remote-file... [ local-file ]
			   Gets a file or set of files from the specified sources.  If the host has already been specified, the source can  be	in
			   the	form of a filename on the remote host.	If the host has not been specified, the source can be a string of the form
			   host:file, specifying both a host and filename at the same time.  If the latter form is used, the last hostname entered
			   becomes the default for future transfers.

       mode		   Sets the file transfer type to network ASCII or binary.  The default type is network ASCII.

       put local-file... [ remote-file/directory ]
			   Puts  a file or set of files to the specified remote file or directory.  If the remote host has already been specified,
			   the destination can be a filename on it.  If the remote host has not been specified, the destination can be a string of
			   the	form  host:filename,  specifying  both a host and filename at the same time.  If the latter form is used, the last
			   hostname entered becomes the default for future transfers.  If the remote-directory form is used, the  remote  host	is
			   assumed to be a UNIX machine.

       quit		   Exits the program.

       rexmt		   Sets the retransmit timer.

       status		   Shows what believes to be the current connection status.

       timeout		   Set the transaction timeout.

       trace		   Sets the packet trace flag.

       verbose		   Sets the verbose mode flag.

Restrictions
       Since the TFTP protocol does not support any authentication, files must be world read (writable) on the remote system.

       Because	there  is  no user-login validation within the TFTP protocol, the remote site should have some sort of file access restrictions in
       place.  The exact methods are specific to each site.
