Faraday::ConnectionFailed: Connection refused - connect(2)

-

When we get some elastic search 9200 port problem :-

Faraday::ConnectionFailed: Connection refused - connect(2) for "domainname.com" port 9200


For solving that issue, open the file

     sudo nano /etc/elasticsearch/elasticsearch.yml

and update the network host:-

     network.host: 0.0.0.0

Then restart the elastic search :-

     sudo service elasticsearch restart

Then your console you can run the command :-

    Product.reindex
