No mysql DB is created on SolidCP IIS installation

I am installing kanboard on solidCP IIS shared hosting server. I have put correct credentials in config.php for mysql db creation with following values
define(‘DB_DRIVER’, ‘mysql’);
define(‘DB_USERNAME’, ‘kan_username’);
define(‘DB_PASSWORD’, ‘passwrd’);
define(‘DB_HOSTNAME’, ‘’);
define(‘DB_NAME’, ‘kan_database’);
define(‘DB_PORT’, null);
define(‘DB_SSL_KEY’, null);
define(‘DB_SSL_CERT’, null);
define(‘DB_SSL_CA’, null);
define(‘DB_VERIFY_SERVER_CERT’, null);
define(‘DB_TIMEOUT’, null);

but strangely it is giving error
Internal Error: SQLSTATE[HY000] [1045] Access denied for user ‘kan_database’@‘’ (using password: YES)

in this error, host IP is different than I entered in config file.
Need help

After changing from mysql to sqlite, kanboard looks working. However, no image is being visible after uploading, neither in avatars, nor in logos, nor even images I attached in tasks. Secondly, email sent shows working but actually no email is being received.
Please help and advise.

For a new installation have resolved db related issues, however, I am unable to view any image (logo, task attachment etc). however pdf attachments work fine. GD is enabled in PHP PHP Info
Can anyone help me in this regard as I am unable to find any help anywhere.
Kind Regards
