Unable to connect to Azure SQL Server from custom edge module.

SqlConnection.Open() が失敗する ModuleBackgroundService.cs の 46 行目から始め、カスタム IoT Edge モジュールのコンテキストで報告された Azure SQL のログイン エラーを確認します。提供されたセットアップで接続の試行を再現し、どの認証または構成の詳細がログイン失敗の原因になっているかを特定します。完了条件は、モジュールが正常に接続を開くこと、または必要な制限事項が文書化されていることです。

Hi Team,

Our customer cannot connect to the Azure SQL server from a custom edge module running on IoT Edge. The custom module gives an error while opening a connection towards the server using the function <conn.Open();>

Please find their below error.
