Cant connect to QNAP MarinaSQL Database. Help request

[MarkNAS2]

Absolute Noob trying to connect to Marina SQL Database on Qnap TP431P3 Remotely any help welcome.
Have set up on my NAS, a working database that I can view and manipulate via phpMyAdmin and website set up as a virtual presence (port 82) that can be browsed at 192.168.1.244:82.
All NAS settings that can be are left at default.
The NAS reports that Web server and MarinaSQL server is running + I have installed Python.
The test database is called “2188329_raspi” and the table “temperature”.
SQLlogin (phpMyAdmin) is “root” and the password “Figureof8SQL! Set by phpMyAdmin ??
Permissions are set for user:
User: 2188329_raspi Password: UltraSlim

Host: % Type: Global: Privileges: All Privileges
----------------------------------------------------------------------------
When using the following script(in the root of the website):
<?php
$mysqli = new mysqli("Localhost", "root", "Figureof8SQL!", "2188329_raspi");
if ($mysqli->connect_errno) {
echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;
}
echo $mysqli->host_info . "\n";

$mysqli = new mysqli("127.0.0.1", "2188329_raspi", "UltraSlim", "2188329_raspi", 3306);
if ($mysqli->connect_errno) {
echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;
}

echo $mysqli->host_info . "\n";
?>

I get: “Localhost via UNIX socket Failed to connect to MySQL: (1045) Access denied for user '2188329_raspi'@'localhost' (using password: YES)”


This is on a local LAN no WAN involved and TCIP connection was selected when setting up MySQL.

I keep all my movie collection in a Qnap TS-451 NAS. I have several TV boxes running Kodi 18 in my home network. I also have an sql server running in my NAS Sharing the movie library.Every Kodi device has a script inside the profile file directing it by IP adress and port number (of my NAS/sql server) to the Data base.Everything works just fine!!! Recently I set up Kodi 18.9 inside the NAS (since it is a media player with HDMI output) I wrote the advanced settings script iside it, but no result!!! Kodi refuses to see the sql database inside the same device!!!! Any suggestions? Thank you in advance!!!
