Hi There, I met some problem while installing elk on 3 different server on Google cloud Platform. First, I build 2 servers based on Debian GNU/Linux 9 (stretch), after installing elasticsearch and kibana respectively, I can `$ curl -X GET http://localhost:9200` and get the result. { "name" : "elastic", "cluster\_name" : "elasticsearch", "cluster\_uuid" : "fV\_t9HRxTl2vrvZLF3EESA", "version" : { "number" : "7.1.1", "build\_flavor" : "default", "build\_type" : "deb", "build\_hash" : "7a013de", "build\_date" : "2019-05-23T14:04:00.380842Z", "build\_snapshot" : false, "lucene\_version" : "8.0.0", "minimum\_wire\_compatibility\_version" : "6.8.0", "minimum\_index\_compatibility\_version" : "6.0.0-beta1" }, "tagline" : "You Know, for Search" } Then because I want to`curl -X GET http://35.225.4.142:9200` through the internet and get the result like above situation. So, the config I only modified at `elasticsearch.yml` as below: network.host: 0.0.0.0 http.port: 9200 But when run `sudo systemctl restart elasticsearch` `sudo systemctl status elasticsearch` Then get error as below: ● elasticsearch.service - Elasticsearch Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Thu 2019-06-06 06:18:04 UTC; 978ms ago Docs: [http://www.elastic.co](http://www.elastic.co) Process: 13477 ExecStart=/usr/share/elasticsearch/bin/elasticsearch -p ${PID\_DIR}/elasticsearch.pid --quiet (code=exited, stat us=78) Main PID: 13477 (code=exited, status=78) Jun 06 06:17:48 elastic systemd[1]: Started Elasticsearch.

Elasticsearch failed to start after some changes you made in the configuration. Can you share the output of `journalctl -u elasticsearch.service` with us ? This will contain necessary information as to what might went wrong. ( Please use `` or (```) to format the log output , you can use the preview panel on the right to see how your post looks like ---

Please format your code, logs or configuration files using `` icon as explained in [this guide](https://discuss.elastic.co/t/about-the-elasticsearch-category/21) and not the citation button.

How about the `elasticsearch.log` contents ? ( not just 10 lines though, but a bit more and covering an attempt to start elasticsearch with the configuration that fails.) ---

It won't show error when i restart the service, but curl Still shows connection refused. ---

This log output is with you using `network.host: 127.0.0.1` though. We know that elasticsearch starts successfully like this and the reason that curl gives you a connection refused when trying to connect is elasticsearch binds to the localhost (127.0.0.1) and by definition is not accessible from outside the server. What we need is the logs from when you set `network.host: 0.0.0.0` and then elasticsearch fails to start. ---
