Hi,
just ran into the problem, that my WebDAV uploads to nginx powered Nextcloud all resulted in 0 bytes files.
There have been several discussions around this topic, i.e. here and here.
After editing /etc/nginx/sites-dietpi/dietpi-nextcloud.conf and changing from
fastcgi_request_buffering off;
to
fastcgi_request_buffering on;
WebDAV sync is fine again.
The comment in the .conf-file sets this off for legacy support- up to now, I can’t find any complications from changing this setting.
DietPi 9.11.2, Nextcloud 30.0.6
