I have tried your suggested solution but it still not working and getting the following error
www-authenticate: Bearer error=“invalid_token”, error_description=“The signature key was not found”

Any suggestion??

also getting this error
contains authorization metadata, but a middleware was not found that supports authorization.
my code is services.AddAuthentication(options => { options.DefaultAuthenticateScheme = OktaDefaults.ApiAuthenticationScheme; options.DefaultChallengeScheme = OktaDefaults.ApiAuthenticationScheme; options.DefaultSignInScheme = OktaDefaults.ApiAuthenticationScheme; }) .AddOktaWebApi(new OktaWebApiOptions { OktaDomain = Configuration["OktaConfiguration:Domain"] });

I gets my token by calling getAccessToken() react js method.
