You may see this error when launching Orchestrate SFDC from Workspace. This is typically caused by an issue with Microsoft Azure relays, which can affect all Access Connect users with on-premise site data in Workspace.
To help diagnose the issue, you can check the browser console for more detail on the underlying error.
Check the browser console

This indicates that the Microsoft Azure relays are not responding correctly. This cannot be resolved without assistance from our support team.
