Website not shown in Google Cloud Platform

I have created a Google Cloud Platform (GCP) account with a domain name from Google Domains, registered with Google. I have created the project, bucket, storage, VM, and uploaded my personal website file(s) and folder(s) to propagate on for viewing. I believe that having followed all of the requested instruction(s) I should be able to view my website. I have also checked for the correct DNS server(s) and resource record(s) for my domain. In all cases when entering the information at the specified locations, I am informed that the information already exists or that there is a conflict error with my entry.

I am hoping that I can find the answers that I need as I have tried several times to contact Google support but to no avail. YouTube video(s) have provided some info but not resolving the issue.

Any assistance would be truly appreciated.
