"Error invoking Hub Method" when starting PPW

Symptoms

The following error appears when starting PPW:

Error: There was an error invoking Hub method 'taskactivationstatus.join'.

Clicking OK clears the message, but it appears the next time PPW is started.


Reason

This error can occur when Rapid-fail protection errors in the WebSocket application pool in IIS exceed the configured limit and cause the application pool to be stopped.

Resolution

Restart the WebSocket application pool on IIS.
