This error indicates that the file was not found on the TFTP server.

Things to try:

* Check that you are attempting to download the correct file.

* Check that you can retrieve the file using an alternative TFTP client, such as tftp-hpa on Linux.

If your TFTP request is constructed using a TFTP URI, then your TFTP server may need you to add an additional slash (/​) character between the server address and the filename. ​ For example:

# Fetch "​images/​pxeboot.nbp"​ from TFTP server 192.168.0.1 
chain tftp://​192.168.0.1/​images/​pxeboot.nbp 

# Fetch "/​images/​pxeboot.nbp"​ from TFTP server 192.168.0.1 
chain tftp://​192.168.0.1//​images/​pxeboot.nbp
