Initial Enum of Domain (AD Module)

So I’m currently stuck on the practice questions underneath the Initial Enum of Domain section - What host is running “Microsoft SQL Server 2019 15.00.2000.00”? (IP address, not Resolved name). I Fpinged the 10.129.0.0/16 address, nmaped the host list, and found two host running this service. Yet no ip I provide the answer box is yielding a correct flag. Can anyone tell me what im doing wrong?

What nmap scan you ran?

Try scanning 172.16.5.0/23 with fping first, then proceed to the next step using nmap with the same command as provided in the example.
