WSO2 Identity Server 5.7.0 Oauth/OpenId Connect Logout has Error about session state?
this is my error:
access_denied opbs cookie not received Missing session state.
and this is my code:
client = new HttpClient();
var response3 = await client.GetAsync("https://localhost:9443/oidc/logout?id_token_hint=" + id_token + "&post_logout_redirect_uri=http://localhost:49545/Home/Contact");
This logout request has to be sent via the browser. If you sent the logout request as a backend request, the relevant cookies will not be passed and the logout will not be processed correctly since WSO2 IS is looking for the the cookies in order to proceed.
