My SQL Error when i put in production: An established connection was aborted by the software in your host machine

My website work normally in localhost but when i upload in production on A2Hosting(With MySQL 5.6) i receive this error.

An established connection was aborted by the software in your host machine

My connection string is:

<add name="Stockphotos_main_db" connectionString="server=70.32.28.70;Port=3306;User Id=<id>;database=<db_name>; password=<password>;Convert Zero Datetime=True" />

I dont know what i do, i try everyting... Look the stack trace:
