I have properly configured jira system properties to enable 2.0 provider for http but still see the 400. Can some one help me to understand if there any other reason for 400 response?

here is my authorize url http://jira-cluster-900-lb:1900/rest/oauth2/latest/authorize?client_id=<my_client_id>&redirect_uri=<my_redirect_uri>&response_type=code&scope=ADMIN&code_challenge=MATx7GZJ2Nc8lNb0rSIr/n1WsxtyBuiyoWOq4k/nYsQ=&code_challenge_method=S256

Thanks,
this was eventually solved by setting up a nginx forward proxy for ssl. Base URL was adjusted as well
