[Neelp Needed] Problems installing

Dear community,

I have a problem installing wordpress into the DB.
This is the link I have from the hosting provider: varsovia.nazwa.pl

I have uploaded all files and folders directly into this FTP directory:
https://ftp.varsovia.nazwa.pl and have configured the wp_config file based on the instructions:

// ** MySQL settings – You can get this info from your web host ** //
/** The name of the database for WordPress */
define(‘DB_NAME’, ‘varsovia’);

/** MySQL database username */
define(‘DB_USER’, ‘varsovia’);

/** MySQL database password */
define(‘DB_PASSWORD’, ‘****************’);

/** MySQL hostname */
define(‘DB_HOST’, ‘sql.varsovia.nazwa.pl’);

/** Database Charset to use in creating database tables. */
define(‘DB_CHARSET’, ‘utf8’);

/** The Database Collate type. Don’t change this if in doubt. */
define(‘DB_COLLATE’, ”);

I have been contacting hosting provider and was told that I need to set up the MySQL 5.5 port to 3307. This is where, they suggest, the issue might be.

How do I do it and how do I resolve the issue?

THANKS!!!!
