I’ve tried this one:
netsh firewall add portopening tcp 4100 MatlabBridge
and it still not work
Then i tried a new one like:
netsh advfirewall firewall add rule name=“MatlabBridge” dir=in action=allow protocol=TCP localport=4100
and it is not help.
Please help, may be somebody know the sollution of this error?

the port is blocked by firewall probably. after I changed the Windows I got the same issue.
