Summary
Minimal example fails when nodes are using IPv6 localhost addresses.
Context
I tried the minimal example at https://hackage.haskell.org/package/distributed-process-simplelocalnet-0.2.4/docs/Control-Distributed-Process-Backend-SimpleLocalnet.html
It works fine on my Windows computer using WSL2 (Windows subsystem for Linux).
But on Linux (Fedora 36), it fails with DiedDisconnect.
Eventually I realised on Linux the nodes are assigned IPv6 localhost addresses (::1).
temporary fix
Disable IPv6 on Linux:

extra reference
past me discovered that Linux would bind localhost as IPv6 only

Perhaps note this down under the troubleshooting section in the doc at https://hackage.haskell.org/package/distributed-process-simplelocalnet-0.2.4/docs/Control-Distributed-Process-Backend-SimpleLocalnet.html .
