I recently installed SSRS 2016 on a Windows 2012 R2 machine and when I go to the Report manager URL I get a blank page. I used the defaults when configuring SSRS except I changed the port from 80 to 8080. The version of SQL Server that SSRS is using is 2016 SP1 and is located on the same server. I'm a local admin on the box. SSRS is installed on the default instance (there is a 2012 and 2014 SQL Server named instance on the box as well but no other installation of SSRS).
The blank page doesn't leave me much to go on in regards to figuring out what the issue is. I've come across a few other posts where people have reported similar issues with the usual cause being changes to virtual directories or insufficient permissions. I don't think that's the issue here but a blank screen doesn't tell me much either way.
Any suggestions on what would cause of a blank page for Report Mgr or suggestions on how to trouble shoot would be greatly appreciated.
