@Ayush_Mathur

can you try running the following aws-cli command using the IAM resource used by filebeat?

```auto
aws s3api get-bucket-location --bucket test-bucket-1-stos

```

As for the config params:  
`endpoint` is not needed if your bucket must not be accessed from a custom domain, like your case  
`default_region` is not supported in filebeat. You can set the env variable `AWS_DEFAULT_REGION` to override it if you want.

If not region is set (either missing or empty `AWS_DEFAULT_REGION` env or setting in `~/.aws/config` or in EC2 instance metadata) `us-east-1` is used as fallback.

This will be the region used for the `GetBucketLocation` request, once we get the region of the bucket we will use it in the following AWS call to that bucket.

`GetBucketLocation` is not region bound: you can perform the request from any region to a bucket in any other regions, and receive a proper result.
