I am trying to add the certificates but this page doesnt exist anymore nor does the wsj one. So how can I get these certificate files so that I can install them onto my Apple TV?
I don't always upload but when I do upload, I upload using just the ip/trailers.cer (NO http prefix required) for example:
192.168.1.101/trailers.cer
When you set the send data to apple to NO then tap (NOT HOLD) play it should put you right in the profile upload screen.

Otherwise if you need to make certs follow this official guide (or if you are using a mac you can optionally use OpenPlex in my signature you have a nas):
The certifictates have never been downloaded, always created
