Searching Within My Sites is Broken


The My Site search is not working.  When trying to search within your my site (, you’re seeing a web page “404 – page not found” (or similar looking) error. 

So What?

This is happening because the UPS (User Profile Service) has a bad URL in the “Preferred Search Center” field.

Now What?

To resolve the issue, in Central Administration, go to the following:

Application Management -> Manage Service Applications -> User Profile Service Application -> My Site Settings -> Setup My Sites -> Preferred Search Center.

Once the Search Center URL is updated, perform a full crawl in the Search Service Application.
