510 Not Extended

After fresh installation of Owncloud on shared hosting server, the Desktop App (2.6.3) tries to send all files to the server. It works with most of the files, but many (>100) files don’t go up, an error is displayed: Server answered with “510 not Extended” to "PUT https://owncloud.homepage.ch/remote.php/dav/uploads/user/…/0000000000000000.
Oddly, I can upload the file in the browser-App (same folder source) without any problem.
The files seem to be randomly selected (jpg, pdf, exe, mp3, mp4, avi, mov…), large and small size, old and newer - I could not find any pattern, which files go and which do not go to the server.
By the way: same behavior when I start the synchronisation from an other PC.

Any ideas?
Thanks for your help!

Hi,

It seems to be a security rules issue …
Could you please attach a screenshot showing the error ?
Please attach also your web Server error log and ownCloud logs

Thanks !

Thanks, Aki.
Luckily the problem was solved after syncing all my other devices (work, laptop etc.) - these did not have the problem…

Best regards!

I am also observing the “510 not extended” issue, and I can work it out.

For me, this started when the server system at my hosting provided was updated. Before I had OwnCloud 8.2, now I have 10.5.0.10. I am running the OwnCloud desktop client 2.6.3 on Debian Linux. I keep seeing sync failures like this (there are hundreds of these messages):

Server replied “510 Not Extended” to “PUT https://myhost.com/owncloud/remote.php/dav/uploads/username/3431728463/0000000000000000

What can I do about this?
