Entity framework cannot connect to the database - asp.net

Question

I have created and hosted an ASP.NET 4 on an exteranl server,it can run fine,but the Entity framework cannot access to the MySQL DataBase.
i can get access to mysql using PHP for exemple [ just to check if the login and Password,and DB's name are corrects],but not with EF.
