Hi,
In the nextcloud12 guide i see the following note:
The default maximum file size for uploads is 512MB. You can increase this limit up to what your filesystem and operating system allows. There are certain hard limits that cannot be exceeded:
< 2GB on 32Bit OS-architecture
< 2GB with IE6 - IE8
< 4GB with IE9 - IE11
Nothing is reported for armhf architecture. But I have some trouble to upload file > 2048MB. Any hints?
