Amazon S3 Bucket中托管的静态Web应用程序突然无法正常工作

Question

The hosted application worked until yesterday but suddenly not working today.

What I have done?

1. Using Cloudfront - To host my website from Amazon's edge locations with a custom SSL certificate setup for my domain.
2. Amazon Certificate Manager - To get HTTPS Certificate

Hosted my client application in S3. They wanted to access their site using a domain name. To achieve this I have provided two records as given below.

Type    Host   Value                         TTL
A       @      IP of the client domain       600

CNAME   www    CloudFront distribution URL   600

The thing is Endpoint which I got while configuring Cloudfront "d3ajo2v2g7lf33.cloudfront.net" is working but the domain name which I added as an alias to this endpoint is not working.

Probable findings from my side:

1) Used let's encrypt to get the SSL and it's about to expire within a week.

2) Added A record with the IP address of the domain. As am using Cloudfront am doubting that the domain does not have a static IP.

Also please let me know CloudFront distribution domain name IP will change every time or will it be static.

Kindly help me to resolve this.

Answer 1

CloudFront has CNAME record as well. So you have to register your domain name in the CloudFront distribution.

as for the SSL certificate for your custom domain, take a look at AWS ACM . It may be easier than using lets encrypt certificate (your call).

and yes. use the cloudfront's domain URL. it won't change unless you delete the distribution.
