Describe the bug:
HI team,
I have single node installation and try to receive a list of indices with pretty common command, but it shows randomly all indices or only hidden like green open .geoip_databases MzFJA4X-Q0a9eElUh1urgQ 1 0 42 0 40.6mb 40.6mb
and in the same time it works normal from any pod in kubernetes with command like

kubectl -n any_namespace exec any_pod_with_curl -- sh -c "curl -s --location --request GET --header  'Authorization: Basic base64_pass' 'http://elastic-master.elastic_ns.svc.cluster.local:9200/_cat/indices'"

If i use postman with port-forward tunnel, i always receive all indices .
There are no any sidecars, injections.
The only difference which i could find is my indices are yellow and .geoip is green

Steps to reproduce:

kubectl -n elastic_ns exec elastic-master-0 -- sh -c "/usr/bin/curl -s -v --location -XGET -H  'Authorization: Basic base64_pass' 'http://127.0.0.1:9200/_cat/indices'"

Expected behavior:
Full list of indices
Provide logs and/or server output (if relevant):

Be careful to obfuscate every secrets (credentials, token, public IP, ...) that could be visible in the output before copy-pasting

Here is the total amount of indices in output

kubectl -n elastic_ns exec elastic-master-0 -- sh -c "/usr/bin/curl -s -v --location -XGET -H  'Authorization: Basic base64_pass' 'http://127.0.0.1:9200/_cat/indices'" | wc -l
