当我的 Azure 辅助角色尝试使用 LINQ-to-SQL 连接到 Azure SQL 数据库以调用 ExecuteCommand 时，我间歇性地收到以下 SQL 异常：
“您尝试连接的 SQL Server 实例需要加密，但本机不支持。”
Google 似乎对此错误消息一无所知。堆栈跟踪显示它在登录前握手期间失败：

我发现了其他类似错误的报告，这些错误是由于登录前握手中的各种问题引起的（其中对于握手中的任何问题，它只是退回到类似的错误消息），以及 SQL Server“强制加密”的其他错误" 需要更改设置，但由于这是一个 Azure SQL 数据库，我无法进入并在 SQL Server 中更改此设置，而且我真的不需要这样做。
由于我在此特定错误上找不到任何其他内容，而且并非每次都发生，因此我不确定在哪里寻找。关于从这里看哪里的任何指示？
编辑：除非另有说明，否则我将这一错误归结为由于来自我的另一个托管服务的数据库服务器上的大量流量而导致的瞬时错误。我问的后续问题中的详细信息：同一服务器上的两个 Azure SQL 数据库能否影响彼此的性能？
