自从我们搬到Azure中，我们看到了几个问题，与我们的数据库。间歇System.ComponentModel.Win32Exception：网络路径找不到
System.ComponentModel.Win32Exception：网络路径找不到
有了这个调用堆栈：
System.Data.Entity.Core.EntityException: The underlying provider failed on Open. ---> System.Data.SqlClient.SqlException: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) ---> System.ComponentModel.Win32Exception: The network path was not found

的recommandation是增加从S0 OU层到S1，这是我们确实，仍然没有帮助。
第二个问题是：
System.ComponentModel.Win32Exception：连接尝试失败，因为连接的方没有正确一段时间后，因为连接主机未能响应响应或已建立的连接失败
第三个是：
System.Data.SqlClient.SqlException：用户登录失败 'MyUserName输入'。
我们尝试：
public class SqlAzureConfiguration : DbConfiguration
{
public SqlAzureConfiguration() {
SetExecutionStrategy("System.Data.SqlClient",() => new SqlAzureExecutionStrategy());
}
}
没有帮助。任何想法是什么问题以及如何解决它？
编辑1：我们的网站现在不停地进行故障。我用DTU的数量进行了屏幕截图。正如你可以看到，我们有20个DTU的，它会持续在一个非常低的使用水平，甚至失败。
EDIT 2
我们怀疑超限会议，我们追踪那些AppInsight，仍然不是问题：
您使用的连接字符串是什么？ （请删除任何敏感信息以保护您的服务器） –
@drediske onnectionString =“Server = tcp：********。database.windows.net，1433; Data Source = *****。database .windows.net; Initial Catalog = Production; Persist Security Info = False; User ID = *****; Password = ****; Pooling = False; MultipleActiveResultSets = True; Encrypt = True; TrustServerCertificate = False; Connection Timeout = 30;” – MBen
不确定是否相关，但是当我们收到Webhook时会发生这种情况。由于我们可以为同一家公司安装一个webhook，所以我们使用了一些锁，这可能是问题吗？ – MBen
