[keycloak-user] Help problem with Bad request

Hello, I have problem with the Bad request when the user login. I have a simple War with JSP-s. With the following keycloak.json { "realm": "test", "realm-public-key": "...", "auth-server-url": "keycloak-url", "ssl-required": "none", "resource": "dashboard-app", "public-client": true, "use-resource-role-mappings": false, "principal-attribute": "preferred_username" } The wildfly redirects to the keycloak perfectly and adds a status parameter to the URL. After the login we get a 400 Bad request error. In the wildfly log I found these lines. WARN [org.keycloak.adapters.OAuthRequestAuthenticator] (default task-111) state parameter invalid WARN [org.keycloak.adapters.OAuthRequestAuthenticator] (default task-111) cookie: 151/af93b54d-6b04-4d82-9a8b-1fe7203b279e WARN [org.keycloak.adapters.OAuthRequestAuthenticator] (default task-111) queryParam: 150/e946fb78-9902-4449-8c33-687fcaf98d3d What did I configure wrong? The Keycloak version is 1.9.8.Final . Any ideas ? Regards
