Cannot connect to WebDAV (Owncloud): "Not a WebDAV enabled share"

[Jason Heeris]

Under 17.04, I had added an Owncloud account to the Gnome Online Accounts under Gnome 3. This created an entry in Nautilus' sidebar that allowed me to remotely browse my Owncloud account. Since upgrading to 17.10, clicking on the entry just brings up an error dialog:

Unable to access "<username>@<servername>"
Not a WebDAV enabled share
[OK]

I get exactly the same error if I type "davs://<servername>/remote.php/webdav/" into the location field.

I had earlier accessed the same server successfully that morning under 17.04, and I'm certain nothing's changed server side. Rebooting doesn't help, installing davfs2 doesn't help, neither does fusedav. I've tried removing and re-adding the account in Online Accounts. The server is accessible via web and the desktop sync client sees it fine.

The server is not internal, it's on the public internet. There is a corporate proxy for which I use CNTLM. But again, this hasn't changed since before the upgrade.

Do you still get the issue? Can you mount the share using "gio mount dav://..."?
It's probably an upstream gvfs? issue and to report on https://gitlab.gnome.org/GNOME/gvfs
