MYSQL rejects my password

[axy_david]

My website URL is:
http://bisaya.rf.gd/index.php

What I’m seeing is:
It seems I cannot access my SQL database, checked the knowledge base too, but to no avail as everything looks fine to me.

This is my code handling connection to the database:

$con = mysqli_connect('sql105.epizy.com','epiz_24668685','************','epiz_24668685_quizworld');
if(!$con)
{
echo 'error connection: ' . mysqli_connect_error();
}

This is the error I get:

Access denied for user ‘epiz_24668685’@‘192.168.2.183’ (using password: YES)

I tried to edit Hosting Account Password to a randomly generated password but to no avail.
It’s funny because FTP works without any problems.
@Admin please help

For debugging purposes I changed my password in the orange box Hosting Account Password.

Edit: OK as per @Grumpy suggestion I just created a new database, that actually solved my troubles, yay!.
It seems the only way to safely circumvent this bug is to change your hosting account password BEFORE creating a database. I’ll leave the other database in case you need to debug it.
