Press F12 in your browser to launch the developer tools. Select the Network tab and recreate the error. See what page it is attempting to browse.

Or look at your IIS logs for the 404 entry. See what HTTP address cannot be found.

If the redirection is done by your code, maybe it can be adjusted.

what is the problem.

The URL is wrong or the page does not exist.

What is the URL in the browser's address bar? Can you share the redirect code?

Thanks for the @AgaveJoe and others.

I have used the below URL

https://avmsvr.avm.avmnet.intranet/Projects120/Login.aspx

Inside Login.aspx.vb Response.Redirect("Home.aspx")

Anything want to concatenate the complete URL in the "Home.aspx" instead of mentioning Response.Redirect("Home.aspx")

Check if this works: Response.Redirect("~/Home.aspx").

What is the URL in the browser's address bar when when the 404 error is shown?

Is "Projects120" configured as a virtual directory in IIS?

Can you explain how authentication works in your application? Are you using Identity? Did you create a custom authentication/authorization?

Hi @AgaveJoe ,

Correct Complete URL : https://avmsvr.avm.avmnet.intranet/Projects120/Apps/

URL : https://avmsvr.avm.avmnet.intranet/Projects120/Apps/WebForm1

Is "Projects120" configured as a virtual directory in IIS?

Yes. "Apps" is Virtual Directory

/Projects120/Apps/ ==> Virtual Path

Can you explain how authentication works in your application? Are you using Identity? Did you create a custom authentication/authorization?
Authentication : Windows Authentication enabled in IIS Identity and custom authentication not used.

Application folder placed in this folder : D:\SVR290\Projects120\Apps\

The same application configured in some other server. It's working fine without any error. Anything blocking https:// in that server....??

A 404 means the page was not found. I'm not sure what you mean by blocking https or how to force such a condition.

Keep in mind, your first URL is "avmsvr.avm.avmnet.intranet/Projects120/Login.aspx". The URL in the browser is avmsvr.avm.avmnet.intranet/Projects120/Apps/WebForm1.

I assume, as the error clearly states, WebForm1 does not exist in the Apps virtual directory. Or maybe it is the other way around and WebForm1 does not exist in the Projects120 folder.

Authentication : Windows Authentication enabled in IIS

Why is there a login.aspx page if Windows Authentication is enabled in IIS? That makes little sense.

I suggest that you use the Fiddler or equivalent tool to see the request and response between the client and server. Difference between IIS Express and IIS might give you a clue to solve the issue.

Hi @Gani_tpt,
Based on the URL in your address bar, the virtual path should be /Projects120/Apps/, not /Projects120/. You need to ensure that your file structure and application configuration match this virtual path. Please check that the /Projects120/Apps/WebForm1.aspx file exists in the correct location. If the file does not exist or has an incorrect filename, a 404 error occurs.

check that IIS is configured correctly to host an asp, net application. the app pool should have the correct framework. also check that the app pool account and the anonymous user account have read access to the files.
