Fix Google AI Project and upload to server

I created my website using Google AI Studio, downloaded the project, and successfully ran it on my localhost without any issues. However, after deploying it to my BigRock hosting server, the website is not working correctly. My domain Styliaa.com is registered with GoDaddy. I suspect the issue might be related to the domain pointing or DNS configuration, but I'm not sure. Could you please check whether I have configured everything correctly, including the domain, DNS records, hosting setup, and deployment? If there are any missing steps or configuration errors, please identify them and guide me on how to fix them. I will not give any access, you have to solve on my PC only via ultra viewer.
