Can't download ZIP with multiple files inside

I found recently that I am not able to download ZIP file created on the fly by Nextcloud with multiple files inside. It is starting downloading file and cut off always in the same place, after 1GB of data. I can download single file even 7GB bit without any issues, but not the zips. I thought that the problem persists only in 15.0.7, but it is exists in 16.0.1 as well. Any idea what this could be?

Nextcloud version 16.0.1
OS: Ubuntu 18.04
Apache: Apache 2.4.39
PHP version: 7.3

There is nothing in the Apache or Nginx (reverse proxy) log files.
