[keycloak-user] Proxy configuration issue

Hi everyone, I am trying to make a simple test and configure a keycloak proxy to protect an application running on http://localhost:8280/backend/ 1. My proxy.json configuration looks like the following: { "target-url": "http://localhost:8280/", "send-access-token": false, "bind-address": "localhost", "http-port": "8080", "applications": [ { "base-path": "/backend", "error-page": "/error.html", "adapter-config": { "realm": "demo", "resource": "sandbox-backend", "realm-public-key": "MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCrVrCuTtArbgaZzL1hvh0xtL5mc7o0NqPVnYXkLvgcwiC3BjLGw1tGEGoJaXDuSaRllobm53JBhjx33UNv+5z/UMG4kytBWxheNVKnL6GgqlNabMaFfPLPCF8kAgKnsi79NMo+n6KnSY8YeUmec/p2vjO2NjsSAVcWEQMVhJ31LwIDAQAB", "auth-server-url": "http://localhost:8180/auth", "ssl-required" : "external", "credentials": { "secret": "9323cdd6-7e0e-46ce-814f-b5ac79581395" } } } ] } 2. I've started the proxy server as specified in the documentation "java -jar bin/launcher.jar proxy.json" I am getting an error "ERROR: UT005026: Jetty ALPN support not found on boot class path, SPDY client will not be available.", but the server still starts, I don't think there should be a problem with that... 3. In the admin console (keycloak running on port 8180) I've configured the backend application like the following: Could you tell me what I am doing wrong? When I put in the app's url in the browser it goes directly to the application... Thanks, Adrian ​
