Hi Team, We have setup GLUU clustering with Nginx as a platform for Load balancing. Problem Statement : With Nginx as LB and running two instances in LB setup. The installation is done as per clustering document below mentioned. (https://gluu.org/docs/ce/installation-guide/cluster/ ) Post performing all the steps mentioned for clustering , the following config was added in Nginx to Load balance requests to the backend. While accessing GLUU admin via nginx we are getting error message on the screen "Error Encountered". If we disable one instance and run only single GLUU. It works fine. This has been clearly identified if we run only single instance it works fine. Running in Clustering mode it gives this error. Nginx Configuration : events { worker_connections 768; } http { upstream backend_id { ip_hash; server sampl1.example.com:443; server sampl2.example.com:443; } upstream backend { server sampl1.example.com:443; server sampl2.example.com:443; } server { listen 80; server_name sample-lb-nginx.example.com; return 301 https://sample-lb-nginx.example.com$request_uri; } server { listen 443; server_name sample-lb-nginx.example.com; error_log /var/log/nginx/error.log notice; ssl on; ssl_certificate /etc/nginx/ssl/httpd.crt; ssl_certificate_key /etc/nginx/ssl/httpd.key; location ~ ^(/)$ { proxy_pass https://backend; } location /.well-known { proxy_pass https://backend/.well-known; } location /oxauth { proxy_pass_request_headers on; #proxy_set_header HOST sample-lb-nginx.example.com; proxy_pass https://backend/oxauth; } location /identity { proxy_pass_request_headers on; proxy_set_header HOST sample-lb-nginx.example.com; proxy_pass https://backend_id/identity; } location /idp/shibboleth { proxy_pass https://backend_id/idp/shibboleth; } location /idp/profile/SAML2/POST/SSO { proxy_pass_request_headers on; proxy_set_header HOST sample-lb-nginx.example.com; proxy_pass https://backend_id/idp/profile/SAML2/POST/SSO; } location /idp/Authn/RemoteUser { proxy_pass_request_headers on; proxy_set_header HOST sample-lb-nginx.example.com; proxy_pass https://backend_id/idp/Authn/RemoteUser; } location /idp/auth-code.jsp { proxy_pass_request_headers on; proxy_set_header HOST sample-lb-nginx.example.com; proxy_pass https://backend_id/idp/auth-code.jsp; } } } Nginx Version : nginx/1.12.2 *********************************************** https://sample-lb-nginx.example.com/oxauth/error ************************************************ Error Logs in application : ==> oxtrust.log <== 2017-12-11 09:01:19,356 ERROR [qtp985655350-12] [org.gluu.oxtrust.exception.GlobalExceptionHandler] (GlobalExceptionHandler.java:54) - Committed javax.faces.FacesException: Committed at com.sun.faces.lifecycle.InvokeApplicationPhase.execute(InvokeApplicationPhase.java:89) ~[jsf-impl-2.2.14.jar:2.2.14] ==> oxtrust.log <== 2017-12-11 09:01:19,357 ERROR [qtp985655350-12] [org.gluu.oxtrust.exception.GlobalExceptionHandler] (GlobalExceptionHandler.java:77) - Can't perform redirect to viewId: /error java.lang.IllegalStateException: Committed Please provide resolution for the same
