Why cannot connect remote report server instance? I have a SQL Server reporting service on ServerR.

I can easily use my local SSMS to connect ServerR's database engine and Reporting Service.

When I try to use my local Reporting Service Configuration Manager, even though I input Server Name as ServerR and click "Find", it shows "No report servers were found."

Why?
If you're using a different version of Reporting Service Configuration Manager, then it wont pick it up.

SSRS Config Manager 2016 doesn't see my local SSRS 2012 instance and vice-versa.
Hope that helps.
