Troubleshoot Google Cloud Storage Bucket HTML Website

Job ID: 38910598

Budget: $10 – $30 USD

I need an experienced Google Cloud freelancer to troubleshoot my issue:

I have created a storage bucket subdomain for a static, HTML website. I have set the CNAME record and made it viewable to the public. I upload a test index.html file but when I go to the root subdomain.domain.com in a browser I get the XML message: "This XML file does not appear to have any style information associated with it. The document tree is shown below."

I am able to view the index.html file by going to subdomain.domain.com/index.html but not the root.

Looking for a quick fix to this which should be an easy solution for an experienced Google Cloud tech (which I am not).
