Anonymous Upload Max File Size

I shared a Folder in a way that you can upload and view files even when not logged in.

As a logged in user i can upload files with sizes however much i set as the server limit.
When trying to upload a 400Mb file as the anonymous user, it either just gives up and does nothing or gets stuck without saying anything.

So basically i want to adjust the max file size an anonymous user can upload.
How would i do that?


Never heard of such a limit for anonymous users.
Does the user that created the public folder has more than 400 Mb available in his account storage ?
