"Unhandled exception: MySql.Data.MySqlClient.MySqlException: access denied for user 'root'@'sfn-inkubator-70-61.hib.no' (using password: YES)" error means that you have established a connection address correctly. The client connects to the server, but the server rejects the username and password combination.
So, you need to check your server settings, create some user with a known password, etc.
