Uploading large files continues to fail

So I am trying to upload a large test file to my NGiNX setup but it keeps failing with an error of 413, entity is too large post_max_size and upload_max_filesize are set to “9G”.

What am I doing wrong?

Nextcloud version (eg, 12.0.2): 13
Operating system and version (eg, Ubuntu 17.04): Ubuntu 16.04
Apache or nginx version (eg, Apache 2.4.25): NGiNX 10.10.3
PHP version (eg, 7.1): 7.2

The issue has been resolved.

Can you post how you resolved it for future users with a similar issue?

could you pls note the solution? thanks

I am having the same problem
What is the solution?

The limit apears to be one mega byte! I have created a variety of files and nothing bigger than one megabyte can be uploaded

The problem was the nginx proxy.
Changing the configuration client_max_body_size to a large value fixed it. By default it barfs at 1M
