No syncing with nextcloud

---

Hi,

I’m new to DAVdroid and I have issues to initially sync my adressbook.
What I did so far:

• Setup server as described in this tutorial:
  https://decatec.de/home-server/owncloud-9-auf-ubuntu-server-16-04-lts-mit-nginx-mariadb-php-7-und-lets-encrypt/
• install DAVdroid and setup davdroid to connect to nextcloud. Apparently, this is working fine
  https://gamesandai.de/nextcloud/s/VVkOB2cYfSXY7EH
• Create some test addresses
• Trying sync them using the manual sync button:
  What I can see from the log and the progress bar is, that there is a connection which times out after two minutes. Unfortunately, I don’t know why, but I AddressBook plugin for thunderbird works fine. Any help is appreciated.

Server Environment:
virtual linux server at HostEurope - Ubuntu 16.04
nginx 1.10.0
nextcloud 11.0.2

InterruptedIOException means that the sync thread was interrupted, which happens when you cancel the sync process manually.

Please create verbose logs where the sync process is not cancelled.

If there’s a server timeout, it’s a networking or server problem. In this case, you should have a look at the server logs and contact Nextcloud support.

Thanks for your quick reply. I did not cancel the sync process. I would even know how to do that, since there is nothing like a cancel button… Isn’t that the verbose log? If not, how do I enable verbose logging?

@mischa There’s a “cancel sync” entry in the Android Accounts activity. Or maybe the sync process is cancelled when you enable and then disable for instance contacts sync while the sync is still running.

Yes, those are verbose logs, but they do not contain useful information because the sync has been cancelled, so we don’t know the real reason why it doesn’t work.

I changed the syncing app and the issue is resolved. Using CardDAV-Sync syncing seems to work fine. But thanks for your help.

@mischa Thanks for sharing the solution.
