Income link checking

Hi,
I’m using twentyeleven theme. I just loged in to my wp admin dashboard today. And I found that it took a long time to load my income link data. Then something pop up unexpected:
RSS Error: A feed could not be found at https://blogsearch.google.com/blogsearch_feeds?scoring=d&ie=utf-8&num=10&output=rss&partner=wordpress&q=link:https://profitsourceblog.com/

Could any one please help me for this?

Thanks!
