Your Elasticsearch network.host is 127.0,0.1 which is localhost so connection can only be made within the host. Change this to 0.0.0.0.

when I changed network.host to 0.0.0.0 ,cannot start elsticsearch service.

sudo systemctl start elasticsearch.service
Job for elasticsearch.service failed because the control process exited with error code. See "systemctl status elasticsearch.service" and "journalctl -xe" for details.

Look at the Elasticsearch logs. It is likely you are hitting some bootstrap checks.
