Invalid JSON in influxdb-php - php

Question

When a query is made, it retuns 404, invalid json error.
I use 8083 as port. Is there any another port for api.
Below is the code I use. Any help is welcome.
<?php
require '/vendor/autoload.php';
$client = new InfluxDB\Client('153.148.25.44', '8083');
$database = $client->selectDB('Meters');
$result = $database->getQueryBuilder()
->select('*')
->from('GDATA')
->limit(2)
->getResultSet()
->getPoints();
//$result = $database->query('select * from GDATAlimit LIMIT 5;');
//$points = $result->getPoints();
//$lastQuery = $client->getLastQuery();
echo '<pre>';
var_dump($result);
?>
Tested database connection, it is working.
Version is 0.13

Answer 1

API port for InfuxDB v0.13 is 8086. I was using 8083, which is used for web.
