title: favicon.ico 503 text/html
body: <p>favicon.ico 503 .netcore iis.
  Only 1 place that references favicon and its in _Layout.cshtml.
  In this file it has type of image but the error in browser says the favicon type is text/html.</p>
  
  <p>Why is this happenning.
  Nothing in my code references the location of favicon shown in the browser error.</p>
