Hello All,
I am able to install Magento2.4 successfully. But while clicking the “Place order” button for a registered user, the below error is displayed in the Exception log -
main.CRITICAL: An exception occurred on ‘sales_model_service_quote_submit_failure’ event: Could not ping search engine: No alive nodes found in your cluster {“exception”:"[object] (Exception(code: 0): An exception occurred on ‘sales_model_service_quote_submit_failure’ event: Could not ping search engine: No alive nodes found in your cluster at /var/www/html/vendor/magento/module-quote/Model/QuoteManagement.php:703, Magento\Framework\Exception\LocalizedException(code: 0): Could not ping search engine: No alive nodes found in your cluster at /var/www/html/vendor/magento/module-elasticsearch/Model/Adapter/Elasticsearch.php:122)"} []

Request for help.

Hi

Magento and elasticsearch is resource hungry. If you are running Magento and elasticsearch on 4g memory,
you may need to upgrade to a larger memory. Check your web hosting.

To debug, start by
Checking how the memory is been used by applications on your server.

I had similar issues. Upgrading the memory from 4g to 8g solved it.
