Problem with files of more than 70 MB

Hallo,
my nextcloud ist running on an webspace (not Server) on www.strato.de
Installation with setup-nextcloud.php
V 15.0.2 - PHP 7.2 ist running on the strato server.
I can access via ftp to the nextcloud directory and over strato to the database.

But: If i want to upload Files with more than 70 MB sometimes i get an error. Download of folders with more than 70MB as zip file fail also.

I did write to the strato support and this ist the answer:

You report a limitation regarding your own NextCloud installation. A server-side restriction for downloads is not on our part. Also by deposited PHP values in this regard, no restriction is given. The reported facts are rather close to a problem of NextCloud installation. If necessary, appropriate adaptation of the scripts are necessary or your used NextCloud version receives a bugfix for the occurring restriction. In this case, the software manufacturer would be the right Nasprechpartner to clarify the matter promptly and as desired.

Has anyone an idea what i can do?

Please have a look on the documentation which describes the relevant parameters.

Thank you for the answer:

First: I have no access to php.ini or apache coniguration file - only i can adjust something in my ftp direktory of /nextcloud/

In the .htaccess i found the following (Upload 1,5gb should bei able?!):

php_value upload_max_filesize 1.9G
php_value post_max_size 1.9G
php_value memory_limit 512M
php_value mbstring.func_overload 0
php_value default_charset ‘UTF-8’
php_value output_buffering 0

SetEnv htaccessWorking true

Anything to adjust?

Lg Stefan
