The RPC server is unavailable when replicate the second Domain Controller

Question

Hello There,

Sorry i'm newbie on managing windows Actove Directory.
We have single AD DC on winserv 2019 with hostname DC1 then we want to make redundancy/fault tolerant to this domain, so we create secondary Domain Controller (DC2) to achieve this goal.
I follow video tutorial on Adding Additional Domain Controller on this youtube video (link)

But, unfortunately after promoting secondary server to a domain controller finished, i checked the DNS Server there is empty/no DNS record on this DC2, not same with the video tutorial.

When i run command repadmin /showrepl, it's show successfully replicate. but
When i run command repadmin /syncall, it's show error like this

"C:\>repadmin /syncall
CALLBACK MESSAGE: Error contacting server <object guid of NTDS
Settings object>._msdcs.<forest root domain>.<top level domain>
(network error): 1722 (0x6ba):
The RPC server is unavailable."

How to properly solved this problem.
I know maybe this fault came from DNS issue, since there is no/empty record on second DC, but how to fix this problem properly?

Thanks, hopefully anyone who can help my problem.
