## Description

### Steps to reproduce

1.  Configure an OAuth application in your OpenProject to allow the OpenProject app to connect
    
2.  Create a new user in OpenProject, log in with them, and set up 2FA (via TOTP)
    
3.  Install the OpenProject app on your phone
    
4.  Open the app and try to connect to your OpenProject as the user from step 2
    

### What is the buggy behavior?

*   Clicking on "Authorize" does nothing
    

### What is the expected behavior?

1.  Clicking on "Authorize" should send the user back to the OpenProject app which should then be connected successfully
