使用以下 yaml 时出现错误。我检查了代码，但我不认为有任何问题。我的结构计划有一个带有 2 个公有子网和 2 个私有子网的 VPC。一个Web服务器实例将放置在公共子网2中。我认为该问题可能与实例创建有关，因为该错误是在实例创建过程中出现的。

安全组仅适用于默认 VPC 或 EC2-classic：
对于非默认 VPC，您必须使用安全组 ID反而。
因此它更好地使用安全组ID.
SecurityGroupIds:
- !GetAtt WebServerSecurityGroup.GroupId
还有你的WebServerSecurityGroup属于默认 VPC，但您的实例位于自定义 VPC 中。你需要VpcId对于您的安全组：
WebServerSecurityGroup:
Type: AWS::EC2::SecurityGroup
Properties:
GroupDescription: Enable HTTP access via port 80 and SSH access via port 22
SecurityGroupIngress:
- IpProtocol: tcp
FromPort: '80'

Your cfn-signal应该是（错误--resource):
/opt/aws/bin/cfn-signal -e $? --stack ${AWS::StackId} --resource WebServerInstance --region ${AWS::Region}
