Anki-sync-server help

Tldr: Hello! I set up an anki sync server on a raspberry pi 4. When I go to the ip:22071, I see a white page with anki sync server on it. How do I see flash cards?

I Used

To get it working since it is for arm64. When I clicked sync on the windows app, it seemed like it worked. But when I go to the ip:22701 I only see anki sync server on a white page. How do I get to see the flash cards. I would like to use it internally only, I don’t like opening things up to the outside.

I also tried logging into the anki android app but it Just said network error or something along those lines. I put both ip addresses where they should have gone. I am not sure if that has something to do with it or will help you.

Thank you very much for your time.
