A couple thoughts,

What about the 'upload_max_filesize'or 'post_max_size' php.ini setting?

Have you verified the permissions on the temp directory specified in the php.ini, 'upload_tmp_dir'?

This is an old post, but this solved the problem for me. I had set the nginx max file size, but PHP was still set at 2M.

Thanks!

This caught me as well, the file I upload was 1.9M last week and over 2M this week, so it failed.

Thanks,
