New description:
In general I would assume that this is a web server related topic, but I
tested it with the official Nextcloud client, RaiDrive and via browser and
the upload went through. Only when using Mountain Duck with online mode
and smart sync mode the upload failed.
It only happens when the file is larger than 900MB or the upload lasts
longer than a specific amount of time.
When the smart index mode is used Mountain Duck will repeatedly try to
upload the file, which causes a constant use of bandwidth.
Tested it with Mountain Duck 4.3 where the file after upload is 0 byte and
with the latest version 4.6 where the file is gone after upload.
The Nextcloud Log tells:
{{{
Error: Cannot modify header information - headers already sent by (output
started at
/home/vhosts/host.com/httpdocs/3rdparty/sabre/http/lib/Sapi.php:132) at
/home/vhosts/host.com/httpdocs/apps/dav/lib/Connector/Sabre/File.php#691
}}}
Like I said, other WebDav clients do not cause this error.
