Problems with LTI access:

* Multiple OpenTA identities or a hash as username ?

   - This has happened for GU students taking Chalmers courses.
   - Make sure you are logged in only through the Chalmers Canvas.

* Access denied  : `Please enable cookies (and third-party cookies) to access OpenTA`

   - Canvas sets third party cookies to open an app in a frame.
   - Enable third party cookies in your browser
   - If you don't want to allow all third party cookies, allow those
     from ``[*.]instructure.com``

* Update your browswer; OpenTA enforces security settings that are
  violated in earlier browswers.

* If you still get problems with LTI access write an email
