I am scratching my head to understand why the same very simple query works fine on one instance (v. 7.6.0) but does not work on my other instance (v. 7.9.3) - I get 404.
curl --location --request GET 'https://(instance_address):9243/_search' \ --header 'Authorization: Basic (instance user/pass)' \ --data-raw ''
When it works (instance A):
When it does not (instance B):
Interestingly enough when I run both queries within Kibana console both queries return valid results.
