Hello, I have an application that requires ElasticSearch as one of its components to work with the application. After successfully installing ElasticSearch, my application wants me to run the CURL -XGET command from another server. When I run the command from another server I get curl: (7) Failed connect to "ipaddressfromESserver":9200 Connection refused. I also get the same error message on the server that has ES installed. ElasticSearch 2.4 is hosted on Red Hat 7.2. What are the potential reasons why I am experiencing this issue? ---

By default Elasticsearch only listens to `localhost`. You may need to set `network.host` to something else. Check out [https://www.elastic.co/guide/en/elasticsearch/reference/6.2/network.host.html](https://www.elastic.co/guide/en/elasticsearch/reference/6.2/network.host.html) ---

Hello when I type "ipaddressfromESServer" in this forum, I am referring to the ip address of the server. What is consider the localhost? Is the 127.0.0.1 address or you referring to the ip address of the where ES is installed? ---

Hello, How can I get it to listen on the ip address that I installed ES? I review the link provided but I dont understand what to do next? ---

If you're not familiar with localhost, then check out [https://whatismyipaddress.com/localhost](https://whatismyipaddress.com/localhost) You need to set `network.host` to something, `0.0.0.0` will bind to _all_ IPs and interfaces on the host, if that is what you want. ---

Thanks for providing the info. I check out localhost earlier. In regards to my issues, I change the network.host to 0.0.0.0. When I enter the following I still receive an error message: [root@OUSNWA2H elasticsearch]# curl -XGET OUSNWA2H:9200 curl: (7) Failed connect to OUSNWA2H:9200; Connection refused [root@OUSNWA2H elasticsearch]# How can I get the curl command to use the servername provided. How can I also used the same command with the servername in the syntax from another server? ---

Please format your code using `` icon as explained in [this guide](https://discuss.elastic.co/t/about-the-elasticsearch-category/21) and not the citation button. It will make your post more readable. Or use markdown style like: ```` ``` CODE ``` ```` Please edit your posts. Anyway your server is listening here on `127.0.0.1:9200`. So the only way to access it is locally with `curl 127.0.0.1:9200/`. If you want to be able to access it from another machine, then you need to configure properly what @warkolm told you > [@Curl: (7) failed to connect](https://discuss.elastic.co/t/curl-7-failed-to-connect/120073/5): > > If you're not familiar with localhost, then check out [https://whatismyipaddress.com/localhost](https://whatismyipaddress.com/localhost) You need to set network.host to something, 0.0.0.0 will bind to all IPs and interfaces on the host, if that is what you want. ---
