#### Post date: [May 3, 2019, 8:39am UTC](https://discuss.elastic.co/t/unable-to-connect-to-elasticsearch-via-localhost-9200/179498/1 "2019-05-03T08:39:17Z")
So I downloaded the .zip file of Elasticsearch 7.0.1 and installed it !
(I followed this tutorial: [https://www.youtube.com/watch?v=YE7AzSCC3E0&t=298s](https://www.youtube.com/watch?v=YE7AzSCC3E0&t=298s))
The current problem is that I can't connect to the localhost!
THANKS in advance!
