pvserver on multiple nodes

Hello,

I try to run pvserver on two nodes (with Ubuntu 20.04) using
mpiexec -n 2 --hosts hostname1,hostname2 pvserver and get an error:

I use ParaView’s binaries downloaded from the website (ParaView-5.9.1-MPI-Linux-Python3.8-64bit.tar.gz). Simple command like mpiexec -n 2 --hosts hostname1,hostname2 hostname works fine. I can also run pvserver on several cores at one node and connect client to it. I have tried to run pvserver on multiple nodes for two different pairs of machines, using mpi from ParaView’s package, and got the same error. Could you please help me with this issue?

Thanks for the help,
Pavel
