OwnCloud service detection failed after migration from 0.9.x

maximilian

Hi,
I just updated to 1.0.4 and can no longer sync with my ownCloud 9 server.
I get the following message “Service detection failed. Couldn’t refresh collection list”
I tried to remove the account then add it again as well as reinstalling the app.
My laptop got stolen and I’m currently on mobile phone only. Please excuse the limited detail, but that’s currently all the information I can provide.

Here is the debug log (I altered the request token and the domain):

rfc2822

When does this error occur? There are no logs (only the erroneous HTTP request), so I can’t tell anything except that OwnCloud returned a 404 Not Found error for PROPFIND /remote.php/carddav/principals/users/maximilian/.

If the “Service detection failed” appears on a sync, the sync has caused a migration to 1.0 and initiated the service refresh. I suggest to add the account again.

If this does not help, please provide steps to reproduce.

maximilian

@rfc2822 I removed and then added the account again as well as removing and reinstalling the entire app. Both didn’t help.
I used the same server before the update without problems. Here is a debug log 0_1459434751200_davdroid-22597-20160331-160830_no_creds.txt

I just added the account and enabled debug logging. This is one of the logs created by what I believe to be the initial synchronization.

Hi,
@Nanu I tried your (by now deleted) suggestion. I didn’t work but thanks for trying to help. I appreciate it.
@rfc2822 I upgraded to 1.0.5 by now but no change. I get the “Service detection failed. Couldn’t refresh collection list” right after clicking on “create account”. The debug log looks like this: 0_1459595843412_davdroid-20333-20160402-103837_no_creds.txt
Neither clicking on the synchronization icon (the two circular arrows) nor using the “Refresh address book list” function produce anything more.

This was different with 1.0.4. See the debug log above.
Cheers

Nanu

@maximilian I realised auto-discovery was working again without the /remote.php/dav/ so deleted. ownCloud was kicking up a 301 error for me after upgrading to 9.0. I’m now having issues with contact sync since upgrading to DD 1.0 so I’ve had to fall back to the cardDav app until I can resolve the issue.

rfc2822

Just wanted to add that OwnCloud 9 has been tested with DAVdroid 1.0 and it works. Are your Contacts and Calendars apps in OwnCloud up to date?

I’m sorry that I can’t give you in-depth OwnCloud support (I don’t have the knowledge for that) – I can just suggest to do some research on your own, maybe ask in the OwnCloud community. I’m sure that OwnCloud 9 (fresh install) works with DAVdroid 1.0, because we have (of course) tested that. There may be 1000s of reasons why there may be problems with exactly your OwnCloud, which was probably updated from previous versions, too. You may try a new user, your, as as a last resort, a fresh OwnCloud 9 installation.

maximilian

@rfc2822 Don’t get me wrong. I’m not saying it’s DAVdroid’s fault. I’m just saying it used to work and now it doesn’t. I have used ownCloud long enough to know that it has a lot of weird behavior.

To be constructive: I found this bug report and the first comment by DeepDiver made me try out different base URLs.
Using the URL https://owncloud.myserver.tld/remote.php/dav/addressbooks/users/maximilian/ worked. I now have a working addressbook (and surprisingly also a working calendar - I expected to have to use calendars instead of addressbooks to get this working but both work with addressbooks).
I’m using ownCloud 9.0.0, with Calendar 1.0 and Contacts 1.1.0.0. These are the latest versions, as far as I know.

@Nanu I hope you get notified when I mention your name here. This could be interesting for you, too.

maximilian

It turns out that my issue was neither DAVdroid’s nor owncloud’s fault. I misconfigured nginx (well-known URLs). It now works with base URL https://owncloud.myserver.tld
Sorry for the noise and thanks for all your help. I appreciate it.
How do I mark this topic as solved?

rfc2822

@maximilian Thanks for the clarification. Flagged the topic as solved.
