Movie cuts out after one second and returns to title page on Roku

I’ve been going insane. I’ve just started using plex and have enjoyed seeing movies like Harry Potter 1 or The Princess Bride in 4K on my TCL S535 TV. I just ripped Alita: Battle Angel from a 4K UHD disk I just purchased and played it on my computer no problem. Plex is on an actual server in a Ubuntu Server VM. I went to play it on my TV and it started playing just fine. As I was figuring out how to prevent it from transcoding (and just getting it to direct play), it started just cutting out immediately after I’d start it playing. It would play for a second and then go back to the title screen of Alita: Battle Angel. I thought maybe it was a bandwidth issue, so I returned to a lower bitrate (as the original said it needed 60 mbps, I have cat 5e cables running between the TV and the server/NAS though so it should be good up to a gigabit) and the problem persisted. I went back to my computer and the file played just fine. When I went through the server logs, I found a line that said “Failed to stream media, client probably disconnected after 227491840 bytes: 104 - Connection reset by peer” shortly after that the session was terminated with reason “Client stopped playback.” I’d like to resolve this somehow so I can use plex and be a subscriber to plexpass, but as is, I’m very frustrated. What can I do to further debug?

To whomever finds this in the future, most smart TVs (my TCL S535 included) only have “fast” ethernet ports, meaning they’re locked at 100 mbps. Using plexpy, I discovered that Alita was being sent at 125 mbps. I bought a Nvidia Shield Pro, used that as my plex client, connected it to ethernet and boom, everything worked perfectly.
