Thingworx composer not loading for IoT modeling


#1

When I click “Launch ThingWorx” for course “IoT Modeling with Thingworx 7.4”, it shows the default splash screen for sometime and throws “Failed to return license click check” and stays in the splash screen. This was working yesterday but not today.
