How to access Neo4j on EC2 from Node

I set up a Neo4j database on an EC2 instance. I attached a domain name and created a certificate so that I can access the browser version from https://my-domain-name:7473. From the browser, I can create nodes and modify the database.

Now I want to be able to modify this database from Node, but it's not working. This is what I have:

const neo4j = require('neo4j-driver');
const driver = neo4j.driver('bolt://my-domain-name', neo4j.auth.basic('neo4j', 'instance-id-password'));
const session = driver.session();

session
    .run(`MATCH (n:User) RETURN n`)
    .then(function (result) {
        result.records.forEach(function (record) {
            console.log(record._fields[0].properties);
        });
    })
    .catch(function (err) {
        console.log('ERROR WITH NEO4J CALL');
        console.log(err);
    });

The error I get is

ERROR WITH NEO4J CALL
{ Neo4jError: Connection was closed by server

I know the cypher query works because when I run this same code replacing my-domain-name with localhost, I get the expected output. So I can't access my Neo4j database unless I am hosting it locally. Any ideas?
