连接 AzureRmAccount ：访问_ws_metadata_exchange_failed

Question

尝试使用 PowerShell 连接到 Azure 时出现以下错误。此帐户以前有效，但不确定发生了什么变化。为组织启用了多重身份验证，但应排除此帐户。这是一个组织帐户；不是 Microsoft 帐户。我在网上发现了类似的错误，但不是这个特定的问题...

Connect-AzureRmAccount –Credential $Credential -Verbose
VERBOSE: Performing the operation "log in" on target "User account in environment 'AzureCloud'".
Connect-AzureRmAccount : accessing_ws_metadata_exchange_failed: Accessing WS metadata exchange failed: The underlying connection was closed: An unexpected error 
occurred on a send.

    + CategoryInfo          : CloseError: (:) [Connect-AzureRmAccount], AadAuthenticationFailedException
    + FullyQualifiedErrorId : Microsoft.Azure.Commands.Profile.ConnectAzureRmAccountCommand

我启用了调试输出以获取更多信息...

Answer 1

问题在于 Connect-AzureRMAccount cmdlet 默认使用 TLS 1.0。集中禁用导致身份验证尝试关闭连接的 TLS 1.0 支持。该问题已通过将以下内容添加到 PowerShell 脚本以强制使用 TLS 1.2 安全协议得到解决：

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
