In order to connect remotely you have to have MySQL bind port: 3306 to your machines IP in my.cnf. Then you have to have created the user in both localhost and '%' wildcard and grant permissions on all DB's as such . See below:
#Replace xxx with your IP Address bind-address = xxx.xxx.xxx.xxx
CREATE USER 'myuser'@'localhost' IDENTIFIED BY 'mypass'; CREATE USER 'myuser'@'%' IDENTIFIED BY 'mypass';
GRANT ALL ON *.* TO 'myuser'@'localhost'; GRANT ALL ON *.* TO 'myuser'@'%';
Depending on your OS you may have to open port 3306 to allow remote connections.
