I am following the Setting up a Static Website Using a Custom Domain tutorial to the letter but something doesn't work and I don't know how to debug it.
Custom domain bought on Namecheap: sankey.app
1/ The DNS of sankey.app is correctly directing to AWS - I can see in debug tools the SOA points to ns-63.awsdns-07.com.
2/ The bucket is correctly configured, the index.html is statically hosted: http://sankey.app.s3-website-us-east-1.amazonaws.com/
3/ The Alias is created (with another one for www.sankey.app, but that should not be relevant).
But http://sankey.app/ returns Connection Timeout and even the protocol changes to https.
Now, I have experimented with https and CloudFront before but it didn't work so I disabled and deleted the distribution. There no active CloudFront distribution associated with the domain or bucket.
How can I debug this situation? I am a newbie and I am really helpless.
