Summary of the issue you are facing:
I’m setting up nextcloud primarily as a quick and easy selfhosted dropbox service with the goal to easily share medium-large(say up to 20G) files with friends and family. Having followed guides by spaceinvaderone I can access the service and upload/download smaller files just fine.
It seems the default limit is 512MB and I have been unsuccessful in figuring out how to change this. Documentation/guides/threads refer to various different files and fields that I cannot find, access, or even exist. Guides seem to be written primarily for other install setups. I’ve tried .htaccess edits, config.php edits, adding a variable in unraid docker GUI, but made no headway. I’m at the point where I think it’s something simple because of my lack of foundational knowledge.
Does anyone know/have a guide that details what I need to know/do specifically for my setup?
