Hi, I am testing Keycloak's Login and Refresh Token with JMeter but getting errors (~1.50% of responses) by refreshing token. Login responses are ok. Path:{server}:8080/auth/realms/customer/protocol/openid-connect/token The JMeter configuration: 20 Threads, Ramp-Up Period: 5 Responses looks like: {"error_description":"Client session not active","error":"invalid_grant"} {"error_description":"Session not active","error":"invalid_grant"} Keycloak is clustered on the server and has 3 nodes. Do you have any idea? Thanks, Kind regards Mustafa Kuru _______________________________________________ keycloak-user mailing list keycloak-user(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/keycloak-user
