Upload 404s on remote Linux server

[mcflyjunior]

Per the above image, I am attempting to import a dd2vtt file from my local PC to the remote linux server, to "worlds/7thknights_pathfinder". Running Ubuntu server 20.04, latest distros and packages, fresh install per the foundry linux wiki instructions

Attempting via Chrome or Firefox, the importer breaks and returns a "404" error before the entire file is even sent over (gauging by task manager network upload speeds). Attempting it locally on my personal foundry install, and it works just fine. Even attempting imports with an old dungeon, and it will not create a webp or normal version of the scene.

It creates a scene ID and then instantly 404s, leaving a blank scene with only doors and lights.

Disabling all modules and running only the importer results in the same issue. I've verified CHmod permissions for the folder/user, ports are open and tcp/udp traffic enabled. Linux packages updated (and installed according to the wiki). Reinstalled the module, issue still persists.

If I manually place the png on the server in the right location, the full scene appears as you'd expect when going through the same process.

I think it is the same issue as #106

Possibly? I have 40mbps upload but it times out within 3-5 seconds of hitting import.
