This was the resolution method after contacting Technical Support: Create a new Windows System variable:

Click on the start icon
Right click on computer and choose properties
On the left hand side of the window click on 'Advanced System Settings'
Click on the 'Advanced' tab if it isn't selected already
Once in the 'Advanced' tab, click on the 'Environment Variables' button
Click on the 'New' button
Add the following values to the window that appears:

The Variable Name: JAVA_TOOL_OPTION
The Variable Value: -Djava.net.preferIPv4Stack=true

Don't go for rubbish like "it's because of JAVA". This happens when MATLAB is blocked by some firewall that is blocking MATLAB from connecting to Internet. MATLAB uses Internet during Stimulation. Just exclude it from firewall and there you go. There will be no error.

I do not know why MATLAB Connector would be involved, unless you are trying to start Simulink over MATLAB Mobile.

But still... see if it helps to install (or reinstall) MATLAB Connector; http://www.mathworks.com/mobile/features.html

I wonder... possibly if you saved a subsystem when you had "connector on" in effect, then it might try to restore the connector when you loaded the module. Hypothetically.

I also can't figure out why MATLAB Connector is referenced. Didn't use / have not used MATLAB mobile prior to this. But only observed it after clicking on "Get add-ons" failed.
