Connect: connection timed out message when creating an index using terraform

[pastibog]

Hello,

We are using this provider to create an Opensearch cluster which works fine but when we are attempting to create an index, after about 6 minutes we get a message that the connection timed out and the terraform fails.
Full message:
Error: Put "<opensearch_endpoint>/<index_name>": dial tcp <ip>:443: connect: connection timed out

Our provider is configured like so:

provider "elasticsearch" {
  url = "https://<opensearch_cluster_endpoint>"
  healthcheck = false
  elasticsearch_version = "OpenSearch_2.7"
  sign_aws_requests = false
  username = <master_username>
  password  = <master_password>
}

I had seen no timeout settings on the provider configuration page so I'd like to ask if there is anything we could do to fix this.
Thanks.
