Your Website is acting not as it supposed to

[blitzdose]

Hi,
the Website you provide https://neinkob.de/grades is giving me following error. I know that DUALIS changed the way that the login works about two weeks ago. Maybe you need to update your API to this new way to login. I'm in DHBW Karlsruhe.

The debugger caught an exception in your WSGI application. You can now look at the traceback which led to the error.
To switch between the interactive traceback and the plaintext one, you can click on the "Traceback" headline. From the text traceback you can also create a paste of it. For code execution mouse-over the frame you want to debug and click on the console icon on the right side.

You can execute arbitrary Python code in the stack frames and there are some extra helpers available for introspection:

dump() shows all variables in the frame
dump(obj) dumps all that's known about the object
