Configuration files for core node give 404 error

I am on the “Configure topology files for block-producing and relay nodes.” At the beginning it tells me to run the wget commands. When wget starts, I get the following errors:

HTTP request sent, awaiting response… 302 Found
Location: (removed as it will not let me post more than 2 links per message)/shelley_testnet-config.json [following]

It would seem the files are not there. Is there another location I can obtain these files?

Note: I had to remove the links because it told me only 2 links allowed per message.

Let’s see if I can add the error in a reply…
