Cannot connect to MySQL online but I can offline

Community support
#1

I cannot get my code to connect to MySQL on this site, but I can connect to MySQL just fine on my local XAMPP instance. I’ve used the credentials my account gave me but still nothing. Below is the code I use and it works for the latest version of MySQL and PHP on XAMPP just not online here.

Any suggestions?

// Create connection
$conn = new mysqli("localhost", "idxxxxxxx_user", "xxxxxxxx", "idxxxxxxx_db");

// Check connection
if ($conn->connect_error)
{
	die("Connection failed: " . $conn->connect_error);
}

EDIT:
Here’s the error code:

Connection failed: ProxySQL Error: Access denied for user ‘idxxxxxxx_user’@‘2a02:4780:bad:f00d::f’ (using password: YES)

Obviously, I have removed my real username, password, and database names for this post.

Any errors are shown?

Are you using the code on your 000webhostapp URL?

If you are trying a script locally to connect to 000webhost MySQL it won’t work.

(you probably know this but I have to say it )

#4

Yes.

Connection failed: ProxySQL Error: Access denied for user ‘idxxxxxxx_user’@‘2a02:4780:bad:f00d::f’ (using password: YES)

#5

No. Locally I’m using XAMPP with my local MySQL db and everything works fine. But when I uploaded all my code to 000WebHost.com and created my db and received my new credentials I updated my code’s credentials to reflect the new ones. But it will not connect and I cannot figure out why.

#6

Do you specify anything about ipv4/6 in your script?

#7

No. I use the code I posted above to test the db connection.

Method 1 — Connecting to the database using PDO (recommended) 

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$database = "database";

try {
    $conn = new PDO("mysql:host=$servername;dbname=$database", $username, $password);
    // set the PDO error mode to exception
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    echo "Connected successfully"; 
    } catch(PDOException $e) {    
    echo "Connection failed: " . $e->getMessage();
    }
?>

Method 2 — Connecting to the database using mysqli (Object-Oriented)

<?php

$servername = "localhost";
$username = "username";
$password = "password";
$database = "database";

// Create connection
$conn = new mysqli($servername, $username, $password, $database);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
?>

Method 3 — Connecting to the database using mysqli_connect (Procedural)

<?php

$servername = "localhost";
$username = "username";
$password = "password";
$database = "database";

// Create connection
$conn = mysqli_connect($servername, $username, $password, $database);

// Check connection
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}

echo "Connected successfully";
?>

I was already using Method 2, I tried method 1 and 3 and still getting the same error.

What is your 000webhostapp URL?

#11

https://mycardatabase.000webhostapp.com/

Just type anything in the login field and click login. It’s a fake login page for now until I get get the db connection working. The error will be displayed at the bottom after you login. It’s for my school project.

#12

Wrong password in config file.

Head to 000webhost.com > Manage > Change Password > set it to the one within config file else make a new password and replicate this into the config file.

#13

I changed it, and updated my config file but it still says the same thing.

EDIT: It took a few minutes after I changed my password for the changes to reflect, but it’s working now. Thank you so much!

#14

Should work fine now, try the first method above.
