I am having issues with synchronizing contacts using Google Exchange Account on Android phone.
As soon as a contact is created or modified on the phone, the changes are not sent back to the server and the entire contact list dissapears.
I am unable to find anything in the logs.
This is printed by zpush.log:
25/11/2017 12:30:52 [ 18] [ INFO] [mary] StatusException: SyncCollections->CheckForChanges(): Timeout forced after 116s from 480s due to other process - code: 3 - file: /var/www/html/lib/core/synccollections.php:579
The error log prints:
25/11/2017 12:28:54 [ 188] [WARN] [mary] Mobile loop detected! Messages sent to the mobile will be restricted to 1 items in order to identify the conflict.
Calendar items sync very well.
Could you please give my any advise on how to fix it?
