Why am I unable to access Splunk web from different country?

[splunkn]

I created AWS EC2 instance and installed Splunk Enterprise on that. Opened all rules for port 8000 and 8089. I can open this Splunk GUI from India. But whenever my peer is trying to open from US he got the message "Server Error". Is this anything related to EC2 security groups? Or password issue? No logs are recording in internal data as well. Could you please us to fix this?

It sounds like a problem with the EC2 security groups.  Verify the settings allow connections from the US peer's IP address.
