This article provides brief information and steps to resolve the following error while downloading a configuration file:
Transfer failed. Reason unknown. TFTP Server Timeout
All ETS versions
The following are guidelines to resolve the issue:
a. Ensure that the TFTP Server has an IP Address that the router can route to. For example, if your network uses a NAT firewall and the router is on the other side of the NAT firewall, then the IP Address of the TFTP Server needs to be the external IP Address.
b. Ensure that you can ping the router from the workstation running the TFTP Server. TraceRoute is a good tool to ensure that there is an open path to the router.
c. Ensure that you can ping the workstation from the router.
