Owncloud_Sub_Url breaks WebDAV

[lumbermatt]

Hi,

I’m setting up Owncloud on my personal server using a Docker instance by following the provided documentation (admin_manual/installation/docker/).
As far I’m using other services, I want owncloud to be available under domainname/owncloud. If I deploy the Docker instance with the OWNCLOUD_SUB_URL env variable set, the PROPFIND verb fails with Error 405 (see the logs below).

Probably I missed something in the configuration (is there a variable that defines a path specifically for WebDAV access?) but I found something conclusive to go on.

I followed the thread with the elements about 40x errors with WebDAV but without success after doing all the checks.

Thanks a lot in advance for the help

Steps to reproduce

1. Create a Docker Instance of Owncloud without OWNCLOUD_SUB_URL set ( / default value)
2. Install and open the Calendar App : works out-of-the-box, I can create calendars and load them on third-party client (KOrganizer, iPhone Calender client)
3. Create a fresh new Docker Instance of Owncloud with OWNCLOUD_SUB_URL set to /owncloud
4. Install and open the Calendar App : don’t work anymore, in the web interface, the calendars do not display (keeps loading with turning circle), third-party client don’t sync anymore

Expected behaviour

Calendar should load on the web interface and allow the third party clients to sync (step 1 and 2) :

Security & setup warnings display a warning : “Your web server is not yet set up properly to allow file synchronization because the WebDAV interface seems to be broken.”

Same beahior occurs occurs when using WebDav with the file part : PROPFIND fails with error 405.

Hey,

i think this could be caused by a current known and documented issue in 10.12.0:

If you have installed ownCloud 10.12.0 in the combination of:

• index.php-less setup
• URL via subfolder

the files view in the web UI will be empty. The desktop app will not be able to sync and an error 405 (Method not allowed) will be thrown. A fix is in progress and will be provided asap. Note that owncloud Server 10.11.0 and earlier are not affected.

Workaround: until the fix is provided, use the .htaccess from your 10.11 backup in your production system.

Hi,

Thank you very much for this advice, I think there is little I had not read in my search for this problem but indeed I must have omitted to look in the release notes.

I had found the same topic on the owncloud-docker github (issue 383) which confirmed that there were other users with this problem.
I have redeployed an instance to 10.11 and it works perfectly and will do until a fix is in.

Thanks and have a good weekend
