warden: could not validate a connection to Elasticsearch. No alive nodes found in your cluster

@ihor-sviziev I already know what the issue was. Elasticsearch version I was using was 7.6, while minimal version built now is 7.10.

Elastic works like a charm after changing it’s version to 7.10

In my case I was upgrading magento from 2.3.6 to 2.4.4. (PHP 8.1, Elasticsearch 7.16) My local environment was Warden on Ubuntu 20.04. To get rid of this error “Could not validate a connection to Elasticsearch. No alive nodes found in your cluster” (that was popping up during bin/magento setup:upgrade) I had to do two things:

1. manually add “elasticsearch” to node <elasticsearch7_server_hostname> in vendor/magento/module-elasticsearch-7/etc/config.xml
2. disable elasticsearch6 and enable elasticsearch7 module

bin/magento module:enable {Magento_Elasticsearch,Magento_InventoryElasticsearch,Magento_Elasticsearch7}

bin/magento module:disable Magento_Elasticsearch6

Hope, that my answer will help someone 😃

Thaks, @TomekWie your answer was helpful and a solution for me.

Trying to make official release working again but no luck.

Elasticsearch image used: docker.io/wardenenv/elasticsearch:7.6 Error on Magento Setup: ElasticSuite : Unable to validate connection to Elasticsearch server : No alive nodes found in your cluster curl -X GET 'https://elasticsearch:9200/' -> curl: (7) Failed to connect to localhost port 9200: Connection refused

Hi,

I have the same issue, I am running a MBP with an M1X Chip, elastic search and redis does not work, for elastic search I got the same error than @hassanas , for redis: qemu: uncaught target signal 11 (Segmentation fault) - core dumped

In both cases, the error is fixed by using latests images from docker hub, on my local (for the time being), I have updated the image in: environments/includes/redis.base.yaml to redis:${REDIS_VERSION:-5.0} And for Elasticsearch, in file: environments/includes/elasticsearcg.base.yaml image: elasticsearch:${ELASTICSEARCH_VERSION:-7.0}

Check the output of warden env logs -f elasticsearch. It may give you a hint what is wrong with your ES instance. Alternatively / additionally, run curl -X GET "elasticsearch:9200/_cluster/health?pretty" inside the Warden shell.
