When running your website in IIS it's associated with an Application Pool. By default this runs under ApplicationPoolIdentity. Try running the Application Pool using a different user (as you would do when running from Visual Studio). See here[^] for more details on how to set it.

I tried 3 other options, but it did not work !

It says Unauthorized which means you have a security issue somewhere.

You'll have to figure that out. I don't have access to your setup.

I am assuming you are using SharePoint client object model to query the data from SharePoint list.

You might have to pass the credentials to the client context.Check if the below code works!

C#

if (isForms)
{
    context.AuthenticationMode = ClientAuthenticationMode.FormsAuthentication;
    FormsAuthenticationLoginInfo fba = new FormsAuthenticationLoginInfo(userName, password);
    context.FormsAuthenticationLoginInfo = fba;
}
else
{
    context.Credentials = new NetworkCredential(userName, password);
}
