Why isn't my link not working in HTML?

So today I tried to make a link with this code
<a href="r.mtdv.me/articles/ugrro">Text</a> and when I clicked it it showed a blank screen.

Code is not working because it is missing the "http://" or "https://" protocol at the beginning of the URL..

To fix this use like this:-
<a href="http://r.mtdv.me/articles /ugrro">Text</a>
