Hi,  
I have a problem with the android app. I can access course’s videos but text and quiz returns me a 404 not found error.  
I didn’t have this problem on native installation. So i debugged the app.  
I discovered that that this url and view

```
# OAuth token exchange
if settings.FEATURES.get(‘ENABLE_OAUTH2_PROVIDER’):
   urlpatterns += [
       url(r’^oauth2/login/$’, LoginWithAccessTokenView.as_view(),
       name=‘login_with_access_token’),
   ]

```

use dot\_models (Django Oauth Toolkit) to validate the user, but in the database the tokens are localted at /admin/oauth2/accesstoken/ not at /admin/oauth2\_provider/accesstoken/.But i have ENABLE\_OAUTH2\_PROVIDER enabled.  
what is going wrong ?

Hi @jefcolbi , and welcome to the community!

Is your problem solved? If yes then no issue else you can check this:

First you need to remove client from [DOP models](http://localhost:18000/admin/oauth2/client) and add them in [DOT models](http://localhost:18000/admin/oauth2_provider/application).

Restart your LMS service and try again. Your access tokens will be saved at:

`<your_site>/admin/oauth2_provider/accesstoken`
