When does this happen?

IF Distributed inference with vLLM and Ray fails due to incorrect network interface selection.

How others solved it

THEN Identify the correct network interface used for inter-node communication via `ifconfig` or `ip addr`, then set the environment variable `GLOO_SOCKET_IFNAME` to that interface name before launching vLLM.

export GLOO_SOCKET_IFNAME=eth2  # replace eth2 with your actual interface name
