Splunk has been installed in a cloud server. Network team has assigned a name to the server, hence referral to the server works only with the assigned name and does not work when referred to as 'localhost' or '127.0.0.1'.
Tried installing the Splunk Add-on for Amazon Web Services, but there is a 403 error in the REST API call:
Setting server name should not cause 127.0.0.1 to be inaccessible. it should always be accessible otherwise this could indicate network configuration issue. also, 403 is indicative of authentication failure and not access issue.
What happens if you ping 127.0.0.1 from the server itself. do you get any reply?
