Hello,
I receive similar error when connecting!
Socket error in call to connect. Connection refused.
( 12.832s) [paraview] vtkClientSocket.cxx:51 ERR| vtkClientSocket (0x13b3800): Failed to connect to server localhost:11111
I tried different versions of pv while the error exists.

Hello,
Yes, I think so. I submit the script provided by the officials of the remote machine.
This is the last lines in the output files when I sbatch the script:

you should connect to this host instead of connecting to `localhost`

OK!! I connect to the host using SSH then I submit the script using sbatch then I establish a tunnel to the local machine using ssh then I try to connect. This is the way the officials asks for. I am not sure which host and when I connect to the host not the localhost?

That command should work assuming the server is running on `exp-4-42.expanse.sdsc.edu` with port `11111`

I did it and even tried another updated operating system (Windows 11). Now I receive another error!

make sure you do not have multiple server running on the host.
