Error using slmsgviewe​r.startCon​nectorIfNo​tRunning (line 455)

Hi, I'm using simulink with an elementary model (a constant and a scope block); when I run it, I read in the command window:

Error using slmsgviewer.startConnectorIfNotRunning (line 455)
Unable to start Matlab connector from Simulink Message Viewer
Error in slmsgviewer (line 58)
Error in slmsgviewer/PersistentInstance (line 297)
Error in slmsgviewer.processRecord (line 397)

If I open the scope, I see the constant value, but this error is very annoying; why this? thanks

I'm getting the exact same message, running a more complicated model. It still runs, but I'd like to know why the error messages come up. Did you ever work out the problem?

I just experienced similar problem with Simulink. The simulation would run, but it would generate many errors in the command window regarding the slmsgviewer.

In my case the problem was the system firewall, which was blocking Matlab.

Once I granted Matlab internet access, the problem was resolved.

Hope it helps.

how did you grant Matlab internet access?

Same problem for me too. Happened so many times.
