Error getting while adding second repository for snapshot

Elastic Stack Elasticsearch
1

Hi, I am trying to add 2 snapshot repositories as s3. Both the buckets are oci buckets. When I added first Bucket it is working fine as expected but when I am trying to add another bucket with different access key and secret key it is showing error while verify.

Below is the screenshot for Elastic Nodes keystore

Details

s3.client.oci_secondary.access_key
s3.client.oci_secondary.secret_key
s3.client.oci_standard.access_key
s3.client.oci_standard.secret_key

oci_standard is working fine. But getting the below error for oci secondary.

Verification status

Not connected

Details

{
  "name": "ResponseError",
  "message": "repository_verification_exception\n\tCaused by:\n\t\ti_o_exception: Unable to upload object [tests-Q0xfvYPcSDGVFFH3aAWCfw/master.dat] using a single upload\n\tRoot causes:\n\t\trepository_verification_exception: [siem-iad02-oci-dr] path  is not accessible on master node"
}

I have used below request to add an snapshot repo in Kibana

PUT _snapshot/siem-iad02-oci-dr
{
  "type": "s3",
   "settings": {
      "client": "oci_secondary",
      "bucket": "bucket_name",
      "endpoint": "Endpoint URL",
      "region": "region", 
      "path_style_access": "true",
      "protocol": "http"
  } 
}

Also both the buckets are in different regions as one is production bucket with client as oci_standard and oci_secondary is DR Bucket which is in different region.
Let me know if any further information required.

Thanks in advance.
