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 https://github.com/owncloud/core/issues/28078 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?

Thanks!
