Docker – Unable to connect to neo4j using python driver but works from neo4j browser

I’m Trying to setup neo4j instance using ec2 as a docker container.
The ec2 is in private subnet and it is accessible using a application load balance.
the load balancer has two listeners one for the browser and another for the bolt.

I can able to connect to neo4j browser UI using a custom domain mapped for alb and I can able to connect to bolt server as well from the browser UI.
The custom domain has ssl cert from ACM.

But when I try to connect to neo4j bolt using the endpoint url I couldn’t able to connect and throwing the below error.

raceback (most recent call last):
  File "/opt/homebrew/lib/python3.11/site-packages/neo4j/_async_compat/network/_bolt_socket.py", line 694, in connect
    return BoltSocket._handshake(s, resolved_address, deadline)

    raise ServiceUnavailable(
neo4j.exceptions.ServiceUnavailable: Cannot to connect to Bolt service on ResolvedIPv4Address(('18.194.47.191', 7687)) (looks like HTTP)

The above exception was the direct cause of the following exception:

Cannot to connect to Bolt service on ResolvedIPv4Address(('52.456.141.61', 7687)) (looks like HTTP)

And I used the below code to connect to the server

from neo4j import GraphDatabase

uri = "bolt+s://neo.mydomain.com:7687"
username = "neo4j"
password = "password"

# Initialize the driver with SSL encryption
driver = GraphDatabase.driver(uri, auth=(username, password))

# Optional: Create a session to interact with the database
with driver.session() as session:
    result = session.run("MATCH (n) RETURN n LIMIT 5")
    for record in result:
        print(record)

# Remember to close the driver when done
driver.close() 

I tried with both bolt+s:// and bolt:// but still no luck.
Below is my docker-compose.yml
