When does this happen?

IF Distributed inference with vLLM and Ray fails because of incorrect network interface selection.

How others solved it

THEN Set the GLOO_SOCKET_IFNAME environment variable to the appropriate network interface (e.g., eth0) before starting vLLM. To determine the correct interface, check available network interfaces using ifconfig or ip addr, and select the one used for inter-node communication.

export GLOO_SOCKET_IFNAME=eth0
