SSO OAuth2 not working, Login Error: AADSTS700016

[mukifl]

Hello Everybody

I recently setup netbox and now wanted to enable SSO for users to sign in.
I went through the documentation and followed the guide step by step but im I am getting below error.

Netbox Version: v3.2.4
Python Version: Python 3.9

I already checked threads on the www and the most common case is, that the application ID is wrong.
I did check the application id many times and copy-pasted the value and its definitely the right one in the configuration.py.

Please find below my configuration.py config:

Any help or suggestions are very much appreciated.

Thank you in advance.

Cheers

The setting names are case-sensitive. You wrote ..._OAUTH2_Key but it should be ..._OAUTH2_KEY
