ownCloud WebDAV interface seems to be broken

Question

I've been trying to host ownCloud on my server but everytime I try to it tells me this :

Your web server is not yet properly setup to allow files synchronization because the WebDAV interface seems to be broken.

Please double check the installation guides.

This is my setup :

Windows Server 2012 R2
IIS 8.5
PHP 5.5.11
ownCloud 6.0.3
MySQL 5.6.17

I tried google the error but I can't seem to find anything usefull.

Some say I should try if this works : https://cloud.mcsoftworks.net/remote.php/webdav/ and yes I can navigate to this folder and I can open files from there.

The calendar works and I can also just upload files from here https://cloud.mcsoftworks.net/ the only thing that doesn't seem to work is the sync client.

The sync client doesn't say anything it just doesn't connect (Screenshot : http://prntscr.com/3p2apz)

This is the error log :

This is my php.ini : http://pastebin.com/es3MB8Uh

Does anyone have any idea on how I should get this to work? I've been trying to get this to work for about 14 days now and it starts to annoy me =P

UPDATE :

Okay so today I installed the newest version of the client on my PC and this client returned an error I think the other client just didn't show this error but the error is :

Error downloading [hostname]/remote.php/webdav/- server replied : Method Not Allowed

Answer 1

The most likely reason for this error is that your server cannot communicate with itself. This could be because your router does not have NAT reflection so your server cannot communicate with itself on its public IP. Try adding a cloud.mcsoftworks.net pointing to 127.0.0.1 in your hosts file (or your internal DNS if you have) so that the server knows to contact itself instead of going out on the Internet.

Alternatively, this could be because your server is not allowing the WebDAV HTTP Verbs through to PHP. See the OwnCloud setup guide for instructions on making sure these settings are set up properly.

As discussed in the OwnCloud forum, the OwnCloud sync client also does not necessarily work with self-signed certificates. Try switching to HTTP temporarily and see if that works. (However, others have gotten self-signed certififcates to work with no problem, and the error you are receiving does not say that this is the issue despite the fact that the symptoms are the same.)

You may also just be having an issue where WebDAV is working properly but the tests are failing, thus preventing WebDAV from working. You can bypass the WebDAV tests in the admin site by adding check_for_working_webdav=false to the config.php file.

Answer 2

Okay, I found out what the problem was. in the IIS 8.5 manager there is a tab called modules if you open that it displays tons of modules search for WebDavModule and delete it.

@Moshe_Katz Thanks for the help.. it pointed me in the right direction.
