Cloudflared server audio files failing to play for some users, "Uncaught (in promise) DOMException: The operation was aborted."

I’m self-hosting a virtual tabletop (Foundry) and have it Cloudflared for other users to access. When accessing through Cloudflare the audio files within the tabletop work for some users and not others; for example one audio file will play for me, but not for other users, and vice versa.

When connecting directly to the server we do not experience this issue and all audio files play as expected.

Below is a screenshot of the console error I’m seeing. I’m on the free Cloudflare plan if that makes a difference.
