Trying to sync Synology NAS via webdav with nextcloud


As topic is saying, I try to sync my Synology NAS via webdav with nextcloud on a dedicated server and I’m even not quite sure if it is a problem with nextcloud.
If I try to connect like this
I get an "Connection denied"
If I misspell the password intentionally I get an "authantication error"
and that’s also the only thing a can see in logging

Warning core Login failed: ‘user’ (Remote IP: ‘’) 2017-10-31T14:29:54+0100

Access via Firefox brings this message:

This is the WebDAV interface. It can only be accessed by WebDAV clients such as the Nextcloud desktop sync client.

Actually I have no idea what I’m doing wrong.

Best regards

Nextcloud version: 12.0.3
Operating system and version: Ubuntu 16.04
PHP version: 7.0.22

As almost always the guy in front of the monitor was the problem.
I was trying to establish a remote connection what seems to a total different story.
Now I’m really using cloud sync and everything works like expected.

I’m sorry for that!

Best regards

Sorry for resurrecting this old post, but I’m exactly in the same place but I do not understand the solution :frowning: SHOULD WebDav not work like that?

You are using Synology Cloud Sync?
I was not and using the right application fixed the problem for me.
