When running listdatasources.bat on the Data Store server, I encounter the error:
Error encountered: 'spatiotemporal' data store is not configured on current machine.

This is strange since I don't have a spatiotemporal data store. We did at one point last year, but the previous employee removed it when before upgrading from 10.9 to 11.1.
So, somehow somewhere, there is still a lingering connection or property that is telling ArcGIS we have spatiotemporal data store (unconfigured though?). I tried using the REMOVE property from the setup.exe installation file, but it gives that same error about an unconfigured spatiotemporal data store.
Setup.exe /qb ACCEPTEULA=YES USER_NAME=mydomain/myaccount PASSWORD=Mypassw0rd
REMOVE=Spatiotemporal

If I run describedatastore.bat, it doesn't list a spatiotemporal data store.
