Access denied for 'user'#'localhost' - php

Question

I'm trying to create model using phalcon. But when I type phalcon model polls I get an error as ERROR: SQLSTATE[HY000] [1045] Access denied for user 'root'#'localhost' (using password: YES).
I can get into mysql using mysql -p. So I tried to create new user and grant him all privileges, but it didn't help. I also can login into phpmyadmin using root and password. I also tried to specify the port as 3306 in config file, but still nothing.
My config file:
defined('BASE_PATH') || define('BASE_PATH', getenv('BASE_PATH') ?: realpath(dirname(__FILE__) . '/../..'));
defined('APP_PATH') || define('APP_PATH', BASE_PATH . '/app');
return new \Phalcon\Config([
'database' => [
'adapter' => 'Mysql',
'host' => 'localhost',
'port' => 3306,
'username' => 'root',
'password' => '$Pass1234 ',
'dbname' => 'poll_db',
'charset' => 'utf8',
],
'application' => [
'appDir' => APP_PATH . '/',
'controllersDir' => APP_PATH . '/controllers/',
'modelsDir' => APP_PATH . '/models/',
'migrationsDir' => APP_PATH . '/migrations/',
'viewsDir' => APP_PATH . '/views/',
'pluginsDir' => APP_PATH . '/plugins/',
'libraryDir' => APP_PATH . '/library/',
'cacheDir' => BASE_PATH . '/cache/',
// This allows the baseUri to be understand project paths that are not in the root directory
// of the webpspace. This will break if the public/index.php entry point is moved or
// possibly if the web server rewrite rules are changed. This can also be set to a static path.
'baseUri' => preg_replace('/public([\/\\\\])index.php$/', '', $_SERVER["PHP_SELF"]),
]
]);
P.S I did all operation about granting privileges entering to mysql by mysql -u root -p
P.P.S I also did FLUSH PRIVILEGES and then restarted mysql, but nothing. Thanks for future help.
UPD: I also tried to created project in laravel, and made migration and everything works fine. I also used root + password.
SOLVED: I don't know why, but I decided to create new project, and everything worked fine even with 'root'#'localhost'. Seems like something wrong was with first project. Even so, thank for all people who participated in helping.
P.S I marked EternHour's answer as solution just for people who might get same error in future.

I don't think this is a port issue, the request is reaching it's destination. Using root#localhost will work when logging in through the command line (mysql -u root -p) but you don't want to use it for connecting with your code. Keep in mind that when establishing your connection, you need to use host=localhost or host=127.0.0.1 explicitly. If you use the IP address (even on the same server), you will get access denied.
[user#localhost ~]# mysql --host=127.0.0.1 --protocol=TCP -u root -p
Enter password:
mysql>
[user#localhost ~]# mysql --host=192.168.1.10 --protocol=TCP -u root -p
Enter password:
ERROR 1045 (28000): Access denied for user 'root'#'hostname' (using password: YES)
Here are the steps I'd recommend taking:
Create a dedicated user that you can use for connecting in your scripts.
If source of script is same server as MySQL.
CREATE USER '<user>'#'localhost'
IDENTIFIED BY 'password';
GRANT ALL
ON <database>.*
TO '<user>'#'localhost';
If the connection is always established from the same place but a different location than MySQL, run the following on the command line.
CREATE USER '<user>'#'<IP_address>'
IDENTIFIED BY 'password';
GRANT ALL
ON <database>.*
TO '<user>'#'<IP_address>';
If the source of the connection varies, run the following command.
CREATE USER '<user>'#'<IP_address>'
IDENTIFIED BY 'password';
GRANT ALL
ON <database>.*
TO '<user>'#'%';
