Solution 1:[1]

Every time you add/edit/remove products, you need to perform a reindex.

php bin/magento indexer:reindex

After re-indexing, everything should work now as intended.

Solution 2:[2]

Sometime you restart your computer, elasticsearch not start, try this command:a

systemctl start elasticsearch.service

php bin/magento cache:flusha

and then reload your page
