Browser is looking for favicon.ico

I was just following TMS video on XData When I run the webclient, both Brave and Chrome are failing because they are looking for favicon.

GET http://localhost:8000/favicon.ico 503 (Service Unavailable)

Whereas the webclient url is

http://localhost:8000/WebClient/Main.html

Question : I dont know why its looking for a favicon. Where do I place the favicon ?

Try to put a favicon. ico in your server root folder

On Googling, it would appear that chrome looks for a favicon by default.

I have put in a blank favicon definition in the html file

<link rel="icon" href="data:,">
