I’m attempting to download a movie (Sicario) for offline viewing, but the download immediately fails when I attempt. So far I’ve tried: Restarting the server, restarting my device, force stopping/clearing cache for the Plex app.
Logs from my Android device attached.

I can see a failure here

This has been identified as may arise when there is DNS Rebinding Protection on the local network
Please see [BUG] Download errors on Android App - Plex Players - Plex Forum
Ah, so if I understand correctly, if I were to set a record on my PiHole (local DNS resolver within my LAN) pointing plex.direct to the IP of my PMS, that should fix it?
No. Tell it to disable “DNS rebinding protection” for this domain.

To disable a security feature on your whole network because Plex can’t implement something correctly? That does not sound nice. Also this block from that link it is a bit strange:
I do not have control of the configurations of all devices in my network. This is very unfortunate, but it is like that. Most devices are implemented in a blackbox/appliance way and the user has no way to change anything. So assuming all devices in my network are safe therefore I can disable a security feature sounds a bit iffy.
Peruse the linked article for background information.
To anyone else who encounters this thread with a similar issue:
My home setup uses a UDM Pro as a router. I have some iptables rules set up on the UDM Pro to force captive DNS to the DNS server of my choice. I do this so that I can force devices which do not obey the DHCP defined DNS servers to still use the defined DNS servers, even if they want to.
Simply put, I am able to force all the devices on my LAN to use my DNS server, whether they want to or not. My DNS server is a PiHole. I observed that when I changed my DNS server from my PiHole to a public DNS server, the issue went away.
I found my solution here: https://www.reddit.com/r/pihole/comments/10285kt/how_to_allow_dns_rebind_for_plexdirect/j3ew2u9/
A fix for DNS Rebinding Protection stopping downloads on Android mobile has now been released in Plex for Android version 9.16.0

Thank you for the update. I like how these kind of things end.
User: There is an X error here
Support: That’s not an error
Three Doritos later:
Support: Here there is a fix the problem X
Thanks anyway, it is highly appreciated that errors are been fixed.
