pvserver with MPI --- reverse connection always refused

Hello there,

I met some problems in connecting to pvserver parallelly running on a cluster. The cluster is Unix system while my ParaView client is on Windows 10.

I tried to run pvserver serially on the cluster and the reverse-connection is successful. When I switched to command

mpiexec pvserver --reverse-connection --client-host=xx.xx.xx.xx ,

I got errors like:

(   1.848s) [pvserver.0      ]          vtkSocket.cxx:447    ERR|vtkClientSocket (0xacd0f0): Socket error in call to connect. Connection refused.

The connection with serial pvserver works fine so I guess it is not the setup problems. Any idea on what’s going wrong?

My ParaView client information is as:

Thanks in advance for any comments.
