after some test and try ,I found that this problem is because of RDC and if you connect to the target machine from one computer with remote desktop connection even if you disconnect all remote desktop and try to debug with Nsight remotely or locally you get this error .
I were connected to the target machine with remote desktop and configure and run Nsight monitor and then close the RDC . and then I tried to debug the project remotely from host on the target and because of it I get this error
I found that one solution will be restart the target machine and configure the Monitor physically at front of the target machine and then DO NOT remote to the target from anywhere, now I can debug my project from host machine on the target machine .
