You aim to host a static website on http://www.example.com using Google Cloud Storage for your staff. After creating a bucket named 'example-static-website', uploading 'index.html' and CSS files, and enabling static website hosting, you set up a CNAME record on http://www.example.com to point to c.storage.googleapis.com. However, accessing the website via http://www.example.com does not display the index page. What is the correct action to resolve this issue?
