Sync error with tasks
Ubuntu Server 16.04, Radicale 1.1.2 behind an NGINX proxy
After adding a Task on my PC with thunderbird (version 52.1.1), DAVDroid gives me the following error: debug.txt. Before that, DAVDroid was working fine, even if I modified (not created) a task with thunderbird. The task where originally created all on Android with OpenTasks.
If I remove from thunderbird the new task, the problem goes away, and I’m able again to synk with DAVDroid
