We are running into a curious issue with users in Guac experiencing extreme lag after opening 3+ connections in multiple tabs. We looked at the /var/log/tomcat8/catalina.out log and we found that our server is not passing the tunnel servlet via websockets.
16:14:22.737 [http-nio-8080-exec-8] INFO o.a.g.t.h.RestrictedGuacamoleHTTPTunnelServlet - Using HTTP tunnel (not WebSocket). Performance may be sub-optimal. We then checked our Nginx web service and made sure all the proper websocket configurations were in place, and it checked out. My next thought was maybe tomcat8 isn't setup properly for websockets. Has anyone had this issue and could reply with some insight?
