Setting up ES on AWS and configuring on XF 2

[PJK]

I'm trying to setup ES on AWS as ES keeps crashing on my server even after a big upgrade. I'm new to all of this, and have a couple basic questions.

In XF, what do I put as the Elasticsearch server and port #? In AWS I don't see the actual server port #, here is what I see in the overview:
https://www.dropbox.com/s/1zmxbm3wand9s7b/Screenshot 2018-09-19 16.26.49.png?dl=0

I see this, but when I put this in it it says "A connection could not be made to the Elasticsearch server.":
https://vpc-xxxxxxxxxx.us-east-1.es.amazonaws.com/
Is a user and pass required?

Here is the access policy:

{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Principal": {
"AWS": "*"
},
"Action": "es:*",
"Resource": "arn:aws:es:us-east-1:327801471504:domain/xxxxxx/*"
}
]
}

When setting up ES on AWS, I left everything as default as there are many configuration options I'm not familiar with. My forum is about 1.25M posts. Are there any good tutorials on what configuration is recommended? I'm looking to get ES working without spending top dollar for it.

Thanks.

Bump, anyone have any tips? For the elasticsearch server I'm using the VPC Endpoint from the AWS ES overview, but it doesn't resolve when clicked. My host opened up ports and I tried them with no luck. What exactly do I use for the Server and Port to get this working?
Thanks.
