Why this is getting max tries exceeded error?

Question

I am reading data from s3 bucket and inserting that data into aws elasticsearch using aws lambda .

If I use request.post then it works.But I need pipeline as a parameter.

  from elasticsearch import Elasticsearch, RequestsHttpConnection
  import boto3
  import re
  import requests
  from requests_aws4auth import AWS4Auth
  region = 'us-east-2'  # e.g. us-west-1
  service = 'es'
  credentials = boto3.Session().get_credentials()
  awsauth = AWS4Auth(credentials.access_key, credentials.secret_key,region, service, session_token=credentials.token)

  host = 'https://search-internship6-aqt7s3tuokjcvx7um3lmm7wvbe.us- east-2.es.amazonaws.com/'  # the Amazon ES domain, including https://
  index = 'lambda-s3-index11'
  type1 = 'lambda-type10'
  url1 = host + '/' + index + '/' + type1

  headers = {"Content-Type": "application/json"}

  s3 = boto3.client('s3')
  #r=requests.get(url=url1,auth=awsauth)
  #print("request ",r)
  #es = Elasticsearch([ 'https://search-internship6-aqt7s3tuokjcvx7um3lmm7wvbe.us-east-2.es.amazonaws.com'])

  print("Hello1")

   es = Elasticsearch(
     'https://search-internship6-aqt7s3tuokjcvx7um3lmm7wvbe.us-east-2.es.amazonaws.com',
    http_auth = awsauth,
    use_ssl = True,
    verify_certs = True,
    connection_class = RequestsHttpConnection
    )  

  # Lambda execution starts here
   def handler(event, context):
#r=requests.get(url= host ,auth=awsauth,headers=headers)
#print("request :",r)

print("es :",es.info())


for record in event['Records']:


    # Get the bucket name and key for the new file
    bucket = record['s3']['bucket']['name']
    key = record['s3']['object']['key']

    # Get, read, and split the file into lines
    obj = s3.get_object(Bucket=bucket, Key=key)
    body = obj['Body'].read()
    lines = body.splitlines()

    # Match the regular expressions to each line and index the JSON
    for line in lines:

        # ip = ip_pattern.search(line).group(1)
        # timestamp = time_pattern.search(line).group(1)
        # message = message_pattern.search(line).group(1)
        print(line)
        # document = { "ip": ip, "timestamp": timestamp, "message": message }
        #r = requests.post(url1, data=line, auth=awsauth, headers=headers)

        es.index(index='internship11', doc_type='packets11', body=line, pipeline='epoch-to-format')
        print("hello2")
        #r = requests.post(url1, data=line, auth=awsauth, headers=headers)
        #print(es.info())

I am getting this error.

ConnectionError(HTTPSConnectionPool(host='https', port=443): Max retries exceeded with url: //search-internship6-aqt7s3tuokjcvx7um3lmm7wvbe.us-east-2.es.amazonaws.com/:443/ (Caused by NewConnectionError (': Failed to establish a new connection: [Errno -2] Name or service not known',))) caused by: ConnectionError(HTTPSConnectionPool (host='https', port=443): Max retries exceeded with url: //search-internship6-aqt7s3tuokjcvx7um3lmm7wvbe.us-east-2.es.amazonaws.com/:443/ (Caused by NewConnectionError (': Failed to establish a new connection: [Errno -2] Name or service not known',))): ConnectionError

Try removing the "https://" from the host name and use the below code

host = 'search-internship6-aqt7s3tuokjcvx7um3lmm7wvbe.us-east-2.es.amazonaws.com'
port = 80

auth = AWSRequestsAuth(
    aws_access_key=credentials.access_key,
    aws_secret_access_key=credentials.secret_key,
    aws_region=region,
    aws_host=host,
    aws_service="es"
)

# Use the requests connection_class and pass in our custom auth class

es = Elasticsearch(
    host=host,
    port=port,
    connection_class=RequestsHttpConnection,
    http_auth=auth
)
