This is the security of tftp.

As you can write to a file without the need for authentication, the correct implementation is that tftp-clients can only write to existing files. In most tftp servers this behaviour can indeed be observed, appearently in yours as well.

Create an empty file on your tftp directory with the filename matching the name that you use to store the config. This will solve your problem.
