私のホスティング プロバイダー (1and1) は、問題は私にあると言っていますが、この問題は DNS の何らかのエラーによって引き起こされていると思います。エラーはコードにあるが、接続するたびにクラッシュすると言われました

接続文字列が原因で同じエラーが発生しました。ポート番号が含まれていましたが、正しい接続文字列は次のようになっている必要があります。

<add name="myConnectionString" connectionString="Server=localhost;Database=mydatabase;Uid=root;Pwd=password;Allow Zero Datetime=true" providerName="MySql.Data.MySqlClient"/>
