I've installed the ThingWorx flow on ThingWorx foundation 9.1.0 , the installer didn't report any error.
But I cannot access https://win-i09msms5m0q:9443/Thingworx/Composer/apps/flow/#/ , the page display : "Thingworx Flow functionality is disabled" .
The thingworx and flow are in the same machine. Logs and screenshot are attached.
OS: Windows Server 2016
Database: PostgreSQL 11
Per the case that was opened, the recommendation was to reinstall Flow. You indicated you were going to be switching to RHEL so it is assumed you did not proceed with the re-installation under Windows.
If you have any additional information to share for other community members, it would be greatly appreciated.
