S4-connector not working but resync works fine

Good Morning Community,

i have an issue with the S4-Connector not working propperly.
We are running an single DC with version 4.4-4 errata587. And it looks like the S4-Connector is running fine but it is acctualy not updating the Samba Objects… What can i do and what do you need to help me?
if i do a /usr/share/univention-s4-connector/resync_object_from_ucs.py --filter uid=xxx the object is synced and works as expected. Any ideas?

and Thankyou in advance for your time

i still can’t make it work anyone a clue?
