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 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 with fping first, then proceed to the next step using nmap with the same command as provided in the example.
