Cause

This is caused by any of the following reasons:

The TFTP server is not running.
The TFTP server is not configured to receive files.
An access list on the router is blocking SNMP requests of TFTP file transfers.
A firewall is blocking TFTP file transfers.
The file transfer request has a specified path name.

Resolution

Check for the following:

Verify that the TFTP server is running.
On the TFTP server, go to File > Configure and verify that the Security and Advanced Security options are not blocking any requests from the router.
Verify that your router's access list includes your machine's IP address. Refer to Configuring IP Access Lists for Cisco devices.
Verify that the firewall allows TFTP requests through port 69.
Verify that a pathname is not specified when transferring files using the TFTP server using the command line. The TFTP server requires the Root Directory to be pointed to be source/destination location. The command should only contain the filename.
