Hello

I’m trying to connect from a ParaView client (5.11.0) on a MacBook to a paraview server on linux (5.11.0) in reverse connection mode and I am getting these errors from the server:

```auto
( 59.285s) [pvserver.0]vtkTCPNetworkAccessMana:395 WARN| vtkTCPNetworkAccessManager (0x86faa0): Connect failed. Retrying for 1.82964 more seconds.
( 60.287s) [pvserver.0] vtkSocket.cxx:459 ERR| vtkClientSocket (0x1966a50): Socket error in call to connect. Connection refused.

```

and the server then aborts.

When I check the ports that my laptop is listening for the connection:

```auto
pascalgrosset@pn2301251 ~ % netstat -an | grep LISTEN
tcp4 0 0 *.11111 *.* LISTEN    
tcp4 0 0 *.53168 *.* LISTEN

```

The exact same pvsc file, shell script that I use on the server, and paraview server work fine if the client is a linux machine but not a mac (M2 MacBook air with Monterey)

Has anyone seen something like this?
