amazon web services - Code: NoSuchBucket

Question

So I've followed the instructions in this excellent guide for setting up a redirect from sub.my-domain.com to my-domain.com/sub. I've checked and double checked my settings, but when I access sub.my-domain.com I get the error

404 Not Found

Code: NoSuchBucket
Message: The specified bucket does not exist
BucketName: sub.my-domain.com

If I go to sub.s3-website-eu-west-1.amazonaws.com (the bucket I created) it is redirected correctly, and I am 100% certain double-plus confirmed that the url in the CNAME Record Set is the correct one. What is going on?

It seems like BucketName in the error message is wrong, but why is this?

Answer 1

It's hard to tell since you (sensibly) obfuscated your question but the way you've written it, I think this is a case of not naming the bucket correctly for this application.

sub.s3-website-eu-west-1.amazonaws.com

If the web site is "sub.example.com," then that's not the correct convention, so I wonder if your bucket name is also not correct: the bucket should be named "sub.example.com" -- not "sub" -- and the web site endpoint should be sub.example.com.s3-website-eu-west-1.amazonaws.com.
