Domain join pending

I have installed UCS (joined in existed active directory domain) and added nextcloud application on it. But domain join script of nextcloud still showing pending status.
I have manualy started “univention-run-join-scripts” command and got this error
Running 50nextcloud.inst failed (exitcode: 1)
Any idea how to resolve this issue ?

What you can see at the join log? “/var/log/univention/join.log”
