Splunk AWS data inputs

[ksi_custr]

Hi

I am trying to collect data from our AWS VPC. I have setup an EC2 instance on that VPC and the Splunk AWS app and addon were installed and configured. IAM role were attached on the said Ec2 instance and the right permission for all inputs were given. However, I am encountering the below error

Is there any configurations that I need to do. I did everything that is describe on the docs and on the below video.

Hi All, for all those whose looking answer for this.
Solved the issue by allowing certain rules on the security groups. the EC2 instance where the addon was installed should be able to access the internet.

Security group rules:
src: your_server
dest: 0.0.0.0/0
dest_port: 443

Hi Splunkers, Do I need to allow certain connections/ports on our firewall?
Thanks

solved the issue on name resolution. But I now get the timed out error when configuring input form CloudWatch Logs.

Any idea on this? Thanks.
