[Samba] Error replica

[Trenta sis]

Hi,

I have on one of two domain controller  executing samba-tool drs
showrepl an error related with replication, error is:

DC=domain,DC=local
        Default-First-Site-Name\SERVER via RPC
                DSA object GUID: 84b48bfd-e3a1-47e2-a825-5965750a2759
                Last attempt @ Wed Jul 19 07:36:56 2023 CEST failed,
result 58 (WERR_BAD_NET_RESP)
                3178 consecutive failure(s).
                Last success @ Mon Jul 17 15:13:58 2023 CEST

I tried to restart samba on both server, but error seems to persist

How can I identify this object or solve the error? What can I do?

Thanks
