Why is the node name `Faraz` when you specify `faraz` in the config? ---

Try to telnet to port 9300 from both host to make sure that is reachable. You can also try to use up addresses for seed hosts to see if that makes a difference. [Next page](https://discuss.elastic.co/t/node-addition-failed/244523.md?page=2)
