Just encounter a problem on SQL Server Reporting Services after installation SQL Reporting on SCOM Server. When perform a test on URL http://servername/ReportServer it displayed below error message:
Based on the information found in this link, it mentioned that SQL reporting failed to initialize due to unmatched installation identifier and public key.
Resolution:-
1. Open Reporting Services Configuration Manager
2. Go to Encryption Key and select Delete
3. Test again. By right, you should be able to get Reporting Server initialize and working fine.
