Can't discover Database when using Reporting studio.

Can't discover Database when using Reporting studio.

Hi Team,
I am using Reporting studio with zenon 14. While connecting to Report engine server I did specify database server as "localhost" and system did discover Server computer name but not showing any database. I have SSMS and I can able to login with ZA2022, Zenon_2022, SQLEXPRESS.
Is there any service we need to look into to discover available database?
Windows firewall is turned off
