Hello.

Trying to install magento 2.4.6 on ubuntu . during magento installation i get the following error 

Could not validate a connection to the opensearch, no alive nodes found in your cluster .

I have search everywhere for solution , yet found nothing that solves this issue. anyone managed to install magento 2.4.6 with opensearch ? if so , please let us know how . 

Thanks.

I think i found the issue. 

Opensearch SSL is self signed and can cause issues on some systems . turning that off in opensearch.yml file allowed me to start magento installation.

If you are getting this error using OpenSearch and your development environment domain is not using SSL (i.e., you're using http instead of https), it's likely that OpenSearch security plugins is causing the issue because it is expecting HTTPS.

**Edit OpenSearch configuration file:**

nano /etc/opensearch/opensearch.yml

**Find and update this line:**

plugins.security.ssl.http.enabled: true

**Change it to:**

plugins.security.ssl.http.enabled: false

**Then save the file and restart OpenSearch:**

sudo systemctl restart opensearch

The OpenSearch cluster is down and isn't finding any working nodes. It won't be able to function until we sort this out. Let's check the servers and get it back up!
