I just installed MS SQL server, IIS and Master Data services, 2016 version. Everything seems fine, except the web application doesn't work. I am able to go to the home screen, but there are no models/versions listed in the Model: and Version: dropdown, even though I added two models using the MDSModelDeploy utility. The UI doesn't give me any error, but Chrome dev tools shows "401 Unauthorised" error.

So basically, the url "http://server-name:port/api/Models" is unreachable, giving "authorization has been denied for this request" error.

I've checked the usual places (allowing anonymous auth etc), they all seem correct. What else should I try?
