正在私有子网中设置Redash实例.EC2状态检查失败

Question

问题摘要

我想在私有子网中设置Redash实例，但效果不好。实例状态检查为"1/2失败"。问题是除了网站上介绍的设置之外，是否还有一些必要的设置(https://redash.io/help/open-source/setup)。

供您参考，如果我将密文实例放在公共子网上，它会很好地工作。

技术细节：

AMI:AMI-060741a96307668be

EC2大小：t2.small

专用子网具有NAT网关

CloudFormation模板如下。(我删除了参数，因为这些是机密信息。参数是正确的，因为我用公用子网检查了这些参数。所以请检查其他部分，谢谢。(

根据marcin的评论，我尝试了下面的模板，但它没有很好地工作，ec2状态检查显示"1/2失败">

我修改了模板，使其能够工作。我只能在我的沙箱帐户中的us-east-1中进行测试，所以我对该区域进行了更改。你需要进一步修改它，因为你的模板是不完整的，我不得不填写很多空白。

模板工作并提供实例(来自curl(：

<div class="fixed-width-page">
<div class="bg-white tiled">
<h4 class="m-t-0">Welcome to Redash!</h4>
<div>Before you can use your instance, you need to do a quick setup.</div>
