Unable to create the report databases (configuration)

Hello Experts,

I was trying to configure reporting service and unable to. The main issues

1. I do not see any databases for reporting service
2. even the SQL Server name is missing
3. I tried to 'change databases' and was required to 'create a new reporting server database'
4. as provided credentials to enable the reporting service connect to Engine it says connection cannot be made (I gave an account that has sysadmin power.... )
5. basically the issue is the reporting server is not able to connect to SQL Server engine

Any help is appreciated in advance
