Hi abfrank,
Did you check the connection using connection string like..
Data Source=166.63.122.xx,3306;Initial Catalog=databasename;User Id=mydatabaseID;password=mypassword

We have no idea what your connection string should be. Contact the MySQL or network admin for assistance.
Also see the MySQL support documentation which has examples for making a connection to MySQL from ASP.NET.
