ISPConfig 3.3.1p1 + nginx + nextcloud

Hi,
since i haven't found working code-snippets to get it working, i'll post mine here.
Add a new website and add to options:
in php.ini

Code:

memory_limit = 8G
upload_max_filesize=15G
post_max_size=15G
max_execution_time = 3600
max_input_time = 3600
opcache.enable_cli=1
opcache.save_comments=1
opcache.revalidate_freq=60
opcache.validate_timestamps = 0
opcache.interned_strings_buffer=256
opcache.memory_consumption=256
opcache.jit = 1255
opcache.jit_buffer_size = 128
output_buffering=0

and the nginx-directive:

Code:

# set max upload size and increase upload timeout:
client_max_body_size 2G;
client_body_timeout 1800s;
fastcgi_buffers 64 4K;
