Yes this was a recent change for the worse to the United website. It has no information on "exception" lounges that are not referenced on the Star Alliance lounge finder. Qatar Air is not in the *A... but UA has a partnership with them and you should be able to use their lounge in Doha when flying UA...or a contract lounge.

This was United.com change just a few days ago.. I'm hoping they restore information for all of their exceptions around the globe..there are a lot of them.
