Im trying to install magento 2.4.6 version in windows system. Installed elastic search 7.17 version and commandline used is below

php bin/magento setup:install --base-url=http://localhost:8082/magento --db-host=localhost --db-host=localhost:3309 --db-name=magento --db-user=root --db-password= --admin-firstname=admin --admin-lastname=admin [email protected] --admin-user=admin --admin-password=admin123 --language=en_US --currency=USD --timezone=America/Chicago --use-rewrites=1 --backend-frontname=admin --search-engine=elasticsearch7 --elasticsearch-host=localhost --elasticsearch-port=9200

But throwing error "Could not validate a connection to Elasticsearch. Unknown 504 error from Elasticsearch null"

Later thought maybe compatability issues and installed elasticsearch8 and tried installation. But same error occured. Please help me to solve this

Make sure your elasticsearch service is running. Use following command

sudo service elasticsearch status

If the service is not running user following command to start it

sudo service elasticsearch start

Please verify first that Elasticsearch active/running in your development system/server.

Magento 2.4.6 also support Open search. So you can remove --search-engine=elasticsearch7 --elasticsearch-host=localhost --elasticsearch-port=9200 from command.
