The target PC 1 is not connecting for real time simulation, what is the solution for it?

Dear sir/Mam,

I'm having trouble for conecting PC 1 on real time explorer,

### Simulink Real-Time Test Suite

### Host-Target interface is: TcpIp

### Test 1, Ping target computer 'TargetPC1' using system ping: ... OK

### Test 2, Ping target computer 'TargetPC1' using SLRTPINGTARGET: ... OK

### Test 3, Software reboot the target computer 'TargetPC1': Error using slrttest (line 160)

TargetPC1: Port is not open.

and

slrttest('noreboot')
