Synchronization doesn't start

gug9sch

Dear all,

I just recognized that my contacts and calendars aren’t synchronize since January this year.

I didn’t get any errors.
When I start the synchronization manually I get the message “Synchronizing now” but from the server logs I see that there was no connection (not even a failed one) and of course no data is synchronized.
I have checked the logs from DAVdroid but couldn’t see any error.
To set up the account again, doesn’t help.
When I click “Refresh address book list” the connection to the server is established as expected (without authentication error).

I’m using the following software:

Do you have any ideas what might be the problems?
Or do you need further information?

I highly appreciate any help.

Regards

Hello,

Did you disable Privacy Guard for DAVdroid?
Is there an “auto-start”, “run in background” etc. permission in Android settings / Apps / DAVdroid / Permissions?
