Error while copying file to target location (Big File)

Hi there,

I have a problem when copying a big file from my Mac nextcloud application to my server. It always shows the following:

I already had a look at different threads but nothing helped. I also increased my php memory size like the following with a custom php.ini:

# Feel free to add and change any settings you want in here.
upload_max_filesize = 20G
post_max_size = 20G

upload_tmp_dir = /var/big_temp_file/

output_buffering = 0

It is mounted to my nextcloud docker image like the following:

    image: nextcloud:latest
    container_name: nextcloud-app
      - /home/mo/mos-nextcloud/custom-nextcloud-php.ini:/usr/local/etc/php/php.ini

Any help is highly appreciated as I need to upload a file which is 15 GB, thanks!

Just a first thought, the client uploads in chunks so the file size limit should not apply in this case. Are you seeing any error logs on the server side?
