Hi all,

I am trying to configure client-server for Paraview and I get the following error (client). The steps I follow for the configuration are:

1. I connect with SSH to the server, there I run pvserver:

`~/OpenFOAM/ubuntu-5.0/run/pvserver
Waiting for client...
Connection URL: cs://ip-XXX-XXX-XXX-XXX:11111
Accepting connection(s): ip-XXX-XXX-XXX-XXX:11111`2.

1. After that on my computer (client) I run Paraview with cs://localhost:11111 but it does not connect, with error (client):

```auto
ERROR: In /home/alpha/OpenFOAM/ThirdParty-v1812/ParaView-v5.6.0/VTK/Common/System/vtkSocket.cxx, line 476
 vtkClientSocket (0x55b9c5188e60): Socket error in call to connect. Connection refused.
```

I do not know what I’m doing wrong and why it does not connect. It is the first time I configure paraview for remote viewing

Thank you
