This message appears whenever the login data (Password / Username) is not correct. 

Please, carefully check the password you entered.

 

Important notice: please note that if your password has the character "." (dot), many smartphones automatically enter a space after the dot, so the password actually sent for authentication is not the correct one.

 

If you have forgotten your password or if your account becomes blocked after several failed attempts, please reset your password. See how to do it Here
