I’ve been running nextcloud on arch linux for months and have never gotten large files to work properly. Gotten dozens of suggestions that haven’t worked. When I try and upload a large file it says something like “Error when assembling chunks. Status code 504.” It will still upload fine despite the warning. When you try and download the large file it will stop every 1GB. Running uwsgi as the application server and nginx as web server.
Below are my conf files. Some of the suggestions other people made are still in them. Some of the suggestions are gone.

nextclpud.ini (for uwsgi) https://pastebin.com/18e1Fwip
nginx.conf: https://pastebin.com/X8GWikHj
