After Upgrade to Magento 2.4.7., setup:upgrade throws "ElasticSuite : Unable to validate connection to Elasticsearch server : No alive nodes found in your cluster"

[constancyGmbH]

We updated Magento from 2.4.6-p8 to 2.4.7-p3.
Now we get "ElasticSuite : Unable to validate connection to Elasticsearch server : No alive nodes found in your cluster" when we run setup:upgrade in the console.

Magento Version : Magento 2.4.7-p3 CE

ElasticSuite Version : 2.11.9.2

Environment : Production Mode

Steps to reproduce

1. Updated Codebase to Magento 2.4.7.
2. run bin/magento setup/upgrade

Expected result

1. bin/magento setup/upgrade runs without an error

Actual result

Updating modules:
ElasticSuite : Unable to validate connection to Elasticsearch server : No alive nodes found in your cluster

@constancyGmbH,

Usually, there are no problems. We are good with Magento 2.4.7/2.4.7-p3 CE.

Probably you doing something wrong during your upgrade.

Are you sure that Elasticsearch is properly configure and running?

Have you checked Magento and Elasticsearch logs?

I have another instance (the live system) connected to the elastic search, so the Server is running and working. maybe there is a problem with the configuration in magento itself. Is there a way to test the connection with my access data from the DB to verify, that there is no config issue?

@constancyGmbH,

Are you sure the Search Engine is set to ElasticSuite in Configuration -> Catalog -> Catalog -> Catalog Search -> Search Engine?

Have you checked Magento and Elasticsearch logs?

Which version of Elasticsearch and which Magento module (magento/module-elasticsearch-7 or magento/module-elasticsearch-8) you are using?

[constancyGmbH]

Yes, it is set to ElasticSuite

We use ES7 (magento/module-elasticsearch-7).

Server Version is 7.17.13

@constancyGmbH,

Have you checked Magento and Elasticsearch logs?

What you have after running this query to DB: SELECT * FROM core_config_data where path like '%elasticsuite%';
