Which means connector has problem to connect to SpectroSERVER

SOI integrated with Spectrum via Spectrum connector.
 

Verify if your SpectroSERVER is running or not.

If the SpectroSERVER is not running:

- Stop Spectrum connector from services.msc
 > CA SAM Integration Services
 > CA SAM Event Management
- Start SpectroSERVER
- Clean Spectrum connector cache ..CA\SOI\lib\ivy\configuration\org.eclipse.osgi
- Start Spectrum connector 

If the SpectroSERVER is running:

- Check ports to ensure nothing is being blocked between the SpectroSERVER and the Spectrum connector systems
- Ensure the Spectrum connector system is added Spectrum's 'Host Security' (.hostrc) file
- Ensure the user used to installed and run the Spectrum connector is a valid Spectrum user in the SpectroSERVER database
