RSS feed TwentyTwelve theme

Hi,

I am trying to create an RSS feed for my blog – so that I can add it to bloglovin for people to find/follow. I installed an RSS widget and put it in my sidebar. I tried using the link: http://www.notlikethemoviesblog.com/feed but it didn’t work. I also tried the RSS feed widget that comes with jetpack and it didn’t work.

I got this error message when I tried the former RSS widget:
RSS Error: WP HTTP Error: Couldn’t resolve host ‘www.notlikethemoviesblog.com’

Can anybody please tell me what this means/how I can fix it 🙁
