Simulink simulation won't start on Raspberry Pi3 in External Mode

I am trying to run my Simulink model in external mode on a Raspberry Pi 3. I went through all of the setup and initial tests for the Simulink support package for Raspberry Pi. I checked to make sure my Raspberry Pi 3 is properly detected by going to Tools --> Run Target on Hardware --> Options, and then checking the "Target Hardware Resources" section. When I click run, the model builds properly and says "build process completed successfully". However, when the model begins to run on the Raspberry Pi 3, it stalls for a second at T = 0.000 s and then the simulation stops. The only message I get is in the matlab command window. See the warning messages below. Why isn't my simulation running on the Raspberry Pi?

Do you have certain firewall settings possibly blocking the connection with the RPi?

I have had this before that it seemed to build and load the application, but External mode immediately stopped when started.
