ParaView reverse connection mode from macbook on VPN error

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:

(  59.285s) [pvserver.0      ]vtkTCPNetworkAccessMana:395   WARN| vtkTCPNetworkAccessManager (0x86faa0): Connect failed. Retrying for 1.82964 more seconds.

and the server then aborts.

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

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?
