title: Sentry api authentication issue
body: <p>I am trying to get all the issues with respect to a project by exposing the sentry api hosted on a private server but getting below response even after using basic auth.</p>
  
  <p>{
    "detail": "Authentication credentials were not provided."
  }</p>
  
  <p>And after generating api key, getting invalid key.</p>
  
  <p>Thanks</p>
