remote connection to a mysql db fail

[migo max]

I wan't to establish a remote connection from PC#2 to a database in PC#1.

PC1:

setup mysql server and workbench.
Set password to the root user, UPDATE mysql.user SET Password = Password('123') WHERE user = 'root';
GRANT ALL PRIVILEGES ON . TO 'root'@'%' IDENTIFIED BY '123';
Create database CREATE DATABASE my_test;
CREATE TABLE info (id int(11), name nvarchar(50));
from ipconfig in cmd get my_ip
Edit my.ini add # bind-address= "my_ip"
from firewall inbound role open 3306.
PC2:

setup mysql server and workbench.
Connect to that my_test: workbench: hostname = my_ip, password = 123, Username = root cmd: mysql -u root -h my_ip -p 123 connection string: Server=my_ip;Port=3306;Database=my_test;UID=root;PWD=123;
and it gives me a jit error :

MySql.Data.MySqlClient.MySqlException (0x80004005): Unable to connect to any of the specified MySQL hosts.

also from cmd in PC#2 :

mysql -u root -h MyIp -p

Error 2003 Can't connect to Mysql server on "myIp"
