" There is no matching data for your input(s)" on all our reports post-migration

" There is no matching data for your input(s)" on all our reports post-migration

I recently migrated our AD Audit and AD Manager server from an on-prem VM to an AWS EC2.

Everything seemed to go fine; I ran the export/import instructions as detailed on the help pages, and everything looked good.

Today though, we were supposed to have our regularly scheduled reports on various topics, and although they were generated, they all just say "there is no matching data for you inputs".

What's even stranger is that when i try to run the reports manually in the console, they do seem to start running, and even generate data on screen, but when they get to the end of the report, the data disappears and I get teh "there is no matching data for your inputs" error.

As far as I can see, our AD service account credentials are correct, because the apps are seeing our DCs and the dashboards actually show data on them; I just don't understand why the reports are coming back empty.

Any help would be appreciated here, these are prtty important reports.
