I've installed eleasticsearch according to the manual provided on [https://www.elastic.co/guide/en/elasticsearch/reference/current/deb.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/deb.html) After starting elastic I tried to check the service: ```auto $ curl -X GET "http://127.0.0.1:9200/?pretty" 503 Service Unavailable

503 Service Unavailable

Failed to connect to server 127.0.0.1 ``` But the service is running: ```auto $ systemctl status elasticsearch.service ● elasticsearch.service - Elasticsearch Loaded: loaded (/lib/systemd/system/elasticsearch.service; enabled; vendor preset: enabled) Active: active (running) since Thu 2020-03-26 13:40:05 CET; 1h 10min ago Docs: http://www.elastic.co Main PID: 14758 (java) Tasks: 41 (limit: 4915) Memory: 4.2G . . ``` The listerner is active: ```auto $ netstat -ntl |grep ':9' tcp 0 0 127.0.0.1:9200 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:9300 0.0.0.0:* LISTEN ``` Elastic log: ```auto [2020-03-27T09:11:09,276][INFO][o.e.n.Node] [elk] closing ...

I have not seen that response before. Do you have a proxy in front of Elasticsearch? ---

Christian, your are right ! The setting ```auto no_proxy=127.0.0.1 ``` was missing in /etc/environment. Thanks a lot ! ---
