This fixed my issue after I enabled SSL on the Orion Web Console, reports that I scheduled would not generate, instead I received this error.
Unable to retrieve url: http://VCAANM01:80/Orion/Report.aspx?ReportID=51 using PDF type.Unable to retrieve url: http://VCAANM01:80/Orion/Report.aspx?ReportID=138 using PDF type.
I updated the details for the Orion server in the SQL table Websites and changed SSLEnabled to 1, and changed the Port from 80 to 443.
All working again! Cheers.
