I'm trying out using Webdav to access a QNAP over the Internet. SMB/VPN was somewhat a little unstable and slow on poor internet connexions. I turned on the Webdav/webserver, I authorised a shared folder to be accessed over webdav by a user, and when I try to connect to the server using command+K on a Mac OS X 10.6.8, I get to accept the certificate (for the secured connexion) and login with my user creditential, but then I get the following message:
There was an error connecting to the server "...". Check the server name or IP address, and then try again.
I tried two different Macs, the other had Mac OS 10.7 I believe, and I tried both on the LAN and over the WAN, same outcome.
I also tried from Cyberduck, and I get:
Error: Not a valid DAV response
I am using the latest firmware: 3.7.3 Build 20120801
Any clue what the issue might be? I feel like I tried everything. Could this be an issue related with the port trunking IEEE 802.3ad?!? (sounds unlikely, but besides that my config is pretty much out of the box, and many people seems to have successfully setup a webdav server and connected with a Mac).
Thanks for your insight!
