If you haven't tried these yet...
1. From Management Console, use the Server Manager to right-click and "Validate" the SASApp workspace server and the Object Spawner. Validate does a little bit more than just "ping" the service.
2. In the Object Spawner properties, verify that the SASApp Workspace Server has been assigned as one the object spawner starts.
After that, I'd probably have a conversation with tech support who can ask and answer questions much more quickly than we can.
🙂 If the above suggestions don't reveal more, it's also quite likely this could be an issue with ports... tech support would be able to guide you on that as well.

(If you call, I would specifically tell them you're having an issue with the object spawner... this issue is more platform admin than EG.)
