Hello,
I am using DAVdroid to sync my calendar and contacts with my synology NAS.
Everything was (and is) running fine with (remaining) android 4.x and 5.x (devices)

Since yesterday I have problems to sync my calendar with android 6.0 (clean install on nexus 6).
Contacts are working fine, but when I sync the calendar the app is terminated.
I do not get any entries from my Caldav server.
When I add a new entry on my android device the new entry is successfully synced to my Caldav server.
I tried to get the verbose logs, but the command:
adb logcat | egrep ‘^(E/)|(./davdroid)|(./HttpClient)|(./Wire)’
does not work on my Windows Computer 
What can I do to get the logs?
By the way:
When I set: “setprop log.tag.HttpClient VERBOSE” what is the default?
I think after getting the logs it should be reverted to default.
Is someone seeing the same error?
Thanks in advance & greetings from germany,
torsten
