samba - Oct 2024 - Problem with a domain controller that is located in a separate site

it seems like I reduced the replication period to 15 minutes between sites
and everything was successful, all connections appeared, I will test this
behavior by creating another samba-based domain controller in a separate
site

I was running samba 4.21 as a domain controller and now I see this situation
, I have empty outbound neighbors, but if you look from the windows side,
then this is the difference between windows controllers and samba, for some
reason the repsTo attribute is not filled, for example, the configuration
context, although windows controllers have both attributes fully filled,
although they are the same there are some on the site, I also attach
screenshots
