Only one of my domains works with Zero Trust

I have 2 domains with Cloudflare and only one of them works with Zero Trust. For example, my primary domain, movies.example.com will not even try to connect to my media server. However, my business domain, movies.example2.com has no issues whatsoever. The configs are the same in zero trust. What else could I be missing or try? I do not want to be using my business domain for my personal stuff but it’s fine as a band-aid I guess
