Kindly, help to get this issues resolved.

Answer 1

I recomend you to enable diagnostics logging for your app. Refer the following article that helps how to configure diagnostics logging in your app.

https://learn.microsoft.com/en-us/azure/app-service/troubleshoot-diagnostic-logs

If you are still facing issues, post the details such as application details, how you are browsing etc.

Answer 2

Hi @Nikunj Chheda we are sorry to hear you're facing this issue. The screenshot you shared provided two reasons why you're getting the 404 Website Not Found" error.

1. Custom Domain Not Configured:
   • By default, Azure Web Apps come with a temporary URL. To use your own domain name (custom domain), you need to configure it within Azure.
   • Refer to Microsoft's guide on how to map an existing domain to your Azure Web App: https://learn.microsoft.com/en-us/azure/app-service/app-service-web-tutorial-custom-domain
2. Client Cache:
   • If you previously accessed the website using its temporary URL, your browser might cache that address. Clearing the cache can often resolve this issue.
   • Here's how to clear the DNS cache for Windows: Open Command Prompt as administrator and run ipconfig /flushdns.

If you've already configured a custom domain and cleared your cache, here are some additional things to check:

• Make sure both the resource group and the web app service are running. You can check their status in the Azure portal. Also make sure that no firewall rules are blocking access to your web app.

Hope that helps.

Best,

Grace
