Orchestrator throwing exception on server when loading webpage (no page displayed)

Getting a pretty hefty error from our Orchestrator service, when trying to view the administration start page - from the exception, it sounds like there is an issue with connection to a licencekey server?

Any chance of some guidance here? It is a fully licensed server on a Windows 2016 Datacenter

*edit - looks like it’s a tls issue?

It was… it was an IIS error - disregard, please.

Hi Morten,

Can you confirm what was the issue on IIS.

I’m facing the same error while connecting Robots to Orchestrator.
