Magento 2.4.1 products not shown in category

Question

I have just migrated by my site form local to server and in the category the products are not visible, i have tried reindexing but not work also when i try to create any new product from backend am getting this is taking too long and error code is 504 while saving it

Also i have checked the logs and got this:-

[2021-01-06 10:32:37] report.CRITICAL: {"error":{"root_cause":[],"type":"search_phase_execution_exception","reason":"all shards failed","phase":"query","grouped":true,"failed_shards":[]},"status":503} {"exception":"[object] (Elasticsearch\Common\Exceptions\ServerErrorResponseException(code: 503): {"error":{"root_cause":[],"type":"search_phase_execution_exception","reason":"all shards failed","phase":"query","grouped":true,"failed_shards":[]},"status":503} at /var/www/html/healthcare/vendor/elasticsearch/elasticsearch/src/Elasticsearch/Connections/Connection.php:665)"} []

elastic search version = 7.9.2 and also when i test it form the backend it is succesfull.

any fix for this. Thanks in advance

update:- also while searching for products am getting this error

1 exception(s):
Exception #0 (Elasticsearch\Common\Exceptions\ServerErrorResponseException): {"error":{"root_cause":[],"type":"search_phase_execution_exception","reason":"all shards failed","phase":"query","grouped":true,"failed_shards":[]},"status":503}

Answer 1

I think it may be an elastic-search version issue. Please try to downgrade the elastic-search version from 7.9 to 7.6.

Answer 2

Magento (2.4.1) is tested with Elasticsearch 7.6.x. You can use other versions at your discretion, but we recommend using the tested version of Elasticsearch.

See the following document for Magento 2 system requirements including Elasticsearch.
