SOLVED: Jellyfin Version 10.9.2: Transcoding Issues with iPhone App

[ca2ju]

Hello, I'm back to wrap up this post, lol. After all these days without giving any feedback, I discovered that Bell Canada is throttling my mobile data, meaning the problem wasn't with Nginx, Apache, Jellyfin, or anything else. How did I find out? At first, when using mobile data, all content was being transcoded. I did several tests on the smartphones of friends, my wife, and family members, and everything worked normally without transcoding. I have NordVPN, and one day I decided to turn it on and... BOOM, it worked perfectly. I tested various countries and had no transcoding issues. I want to thank TheDreadPirate for the attention, thank you very much!

If anyone knows how to bypass this, it would be great, because now the Jellyfin app on my iPhone doesn't even work when I use mobile data. I might have to file a complaint with Bell or switch carriers.
