Creating shares not working - configs are not created in /etc/samba/shares.conf.d/

Hello. I tried fixing this but running out of ideas.

On my domain, I am able to create shares on various domain controller backup servers, except one.

I can create the share via web UI, and it shows OK, however actual share is not created, and there
are no configs generated in /etc/samba/shares.conf.d/ directory.

How can I fix this please?

If this is any help, I found this command on this forum and ran on affected server:

$ univention-directory-listener-ctrl status samba-shares

# and in the output I saw this line in red
0       samba-shares    /usr/lib/univention-directory-listener/system/

ran this command on another server and it shows samba-shares in green with number 3 in front.

How can I continue troubleshooting from here?
