I did an in place upgrade from SQL2008R2 SP3 to SQL2016. Everything went fine with the upgrade, however SSRS isn't working. It starts fine (SSRS service running) however I can't access the reports page. When going to SSRS Config. Manager, the "Report Server Instance" box is empty and greyed out (can't key into it). When clicking Find, I get a message that there are no report servers found. I tried changing the compatibility level of ReportServer and ReportServerTemp to 130 (it was left at 100 after the upgrade). This didn't help. I've rebooted the server a couple times. Still no luck. Does anyone have any ideas?
