Client calendar apps (Evolution, Android calendar) only syncs some events

Steps to reproduce

  1. Create event in calender (use a client or the web-gui)

Expected behaviour

The event should show up in all clients.

Actual behaviour

The event exist when I look at the web-gui. But not at the clients.

Server configuration

Operating system: Ubuntu 16.04

Web server: Apache 2..4.18

Database: Mysql 5.0.12

PHP version: 7.0.18

ownCloud version: (see ownCloud admin page): 9.1.6

Updated from an older ownCloud or fresh install: 9.1.5

Where did you install ownCloud from: Ubuntu repository

Signing status (ownCloud 9.0 and above): Fine

Look at to see the config etc. I have found out that the problem is not connected to the setup or to the sync itself (I ran the litmus, and it worked fine).

The clients sync a number of events, but stop at some point.
I can create events in another calendar at the server, and they get synced to the clients I connect to that calendar.

  • I guess an event is broken, but I am not able to track down which one it is.
    Where is the events situated? And does anyone have an idea what to do in order to find the broken event?
