Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Applicability

Splunk Cloud

Description

If network policy restricts users only to <stack>.splunkcloud.com domain then will be unable to open: 
Settings > Server settings > IP allow list configuration page.

Users will receive: 
404 NOT FOUND
403 FORBIDDEN
HTTP errors (or similar errors depending on network security product configuration).
 

Investigation

Users should verify that can open ACS REST API "https://admin.splunk.com" in their web browser.

The expected output is: 
{"code":"404","message":"Not Found"}
(this is not an error, because it is a REST API, not a web page).

If users see anything different, it means the page is blocked.
 

Resolution

Reach out to the network team or other team responsible for network security configuration, to request to allow access to ACS API URL https://admin.splunk.com in the firewall or network security product blocking it.
