AWS S3 static website: Error 400: The specified bucket exists in another region

Question

I have created static website http://librarysystest.bi.nu in AWS S3. The bucket librarysystest.bi.nu was created by cloudformation. The website contains video which can be accessed via URL: https://s3-eu-west-1.amazonaws.com/librarysystest.bi.nu/7Ys_yKGNFRQ.webm

I have created A-Record in Route53 librarysystest.bi.nu pointing to s3-website-eu-west-1.amazonaws.com.

But the URL http://librarysystest.bi.nu/7Ys_yKGNFRQ.webm gives me the error

400 Bad Request Code: IncorrectEndpoint Message: The specified bucket exists in another region. Please direct requests to the specified endpoint. Endpoint: librarysystest.bi.nu.s3-website-eu-west-1.amazonaws.com RequestId: 602764FBC4BD93D4 HostId: N1EOt05Qfrc/u/+ny/ADfOY0Vvmr/Tg4oqFBiY/Wfv9h2hznGicyj8pOI4MsY5YocexGrhd/D90=

I have created static websites before but this is the first time I am facing a problem. Can someone spot the problem?

Answer 1

Found the issue soon as I posted the question. I didnt add the index.html, didn't think that was important. Curiously, I added the file and (abracadabra) it worked.

This is for someone who might be scratching his/her head for hours.. like I did :)
