Versions (relevant - OpenSearch/Dashboard/Server OS/Browser):

Describe the issue:
Im trying to create snapshots from my opensearch to my bucket on s3,
my opensearch installation is on helm chart, and in my custom dockerfile i added the s3.default.access_key and secret_key of my bucket to the opensearch-keystore as in the docs.
when trying to create the snapshot using the dev tools im getting this error:
403-access denied,

Configuration:
_snapshot/my-repo
{
bucket: “my-bucket”,
base_path: “snapshots”,
region: “us-east-1”
}

when using the access key and secret key in postman i can successfully access the bucket.

Hi @idan17,

How did you configure it?

Have you followed the steps as per: Take and restore snapshots - OpenSearch Documentation
