neo4j graphaware php-client: Connection refused

I am running XAMPP locally on my MacBook. On the same computer, I run neo4j Enterprise. The database is version 3.5.6.

When I try to connect to the database through the php client, I get a warning and a fatal error:

Warning: stream_socket_client(): Failed to connect to tcp://localhost:7687 in /opt/lampp/htdocs/avi-law_codetest/vendor/graphaware/neo4j-bolt/src/IO/StreamSocket.php (connection refused) 203

Fatal error: Uncaught GraphAware\Bolt\Exception\IOException: Error connecting to server (111): " in /opt/lampp/htdocs/avi-law_codetest/vendor/graphaware/neo4j-bolt/src/IO/ Connection refused" StreamSocket.php: 207 Stack trace: #0 /opt/lampp/htdocs/avi-law_codetest/vendor/graphaware/neo4j-bolt/src/IO/StreamSocket.php(245): GraphAware\Bolt\IO\ StreamSocket->connect() #1 /opt/lampp/htdocs/avi-law_codetest/vendor/graphaware/neo4j-bolt/src/Driver.php(133): GraphAware\Bolt\IO\StreamSocket->reconnect() #2 /opt/lampp/htdocs/avi-law_codetest/vendor/graphaware/neo4j-bolt/src/Driver.php(115): GraphAware\Bolt\Driver->handshake() #3 /opt/lampp/htdocs/avi-law_codetest /vendor/graphaware/neo4j-php-client/src/Connection/Connection.php(192): GraphAware\Bolt\Driver->session() #4 /opt/lampp/htdocs/avi-law_codetest/vendor/graphaware/neo4j-php-client/src/Connection/Connection.php(109): GraphAware\Neo4j\Client\Connection\Connection->checkSession( ) #5 /opt/lampp/htdocs/avi-law_codetest/vendor/graphaware/neo4j-php-client/src/Client.php(220): in /opt/lampp/htdocs/avi-law_codetest/vendor/graphaware/ neo4j-bolt/src/IO/StreamSocket.php on line 207

The same story has changed https(just with the other two ports in the error statement).

I have checked Username(neo4j) and (Neo1234) to the database through the browser interface . Both are correct. I also tried replacing "localhost" with the IP address of the Apache server.password

require_once 'vendor/autoload.php';

use GraphAware\Neo4j\Client\ClientBuilder;

$client = ClientBuilder::create()
//->addConnection("default", "http://neo4j:Neo1234@localhost:7474")
->addConnection('bolt', 'bolt://neo4j:Neo1234@localhost:7687')
->build();

$query = 'MATCH (user:User {name:"john"})
CREATE (friend:User {name:"Judith"})
MERGE (user)-[r:FRIEND]->(friend)
RETURN user, friend, r';

$result = $client->sendCypherQuery($query)->getResult();

$john = $result->get('user');
$judith = $result->get('judith');

// What john has for relationships

print_r($john->getRelationships()); // returns relationships objects

If a var_dump() is performed on the $client variable, the result is as follows:

The settings in neo4j.conf are in their default state.
