Resolution:
This error is thrown by CAMDM API Service in the context of connecting to Farm. When CAMDM tries to get the server context details and if its not available, then it tries to initialize, if this initialization fails again then this exception is thrown.

Because in their case, the Master is offline and being rebooted, this is expected. This should go away once the Master is up in normal state.
