@Taddeusz I agree with you. However, if I stop the docker, my firewall stop report abnormal traffic. I remove and reinstall, the problem still exist.

Anybody has this issue where Guacamole docker try to access these IP? My firewall blocks them.

Is there anyway to pass real ip to nextcloud log when log in to nextcloud? Currently, I have nextcloud behind letencrypt.

Thank you. This solves my reverse proxy warning.

Oh I need to kick myself. I got it. I put in the wrong place.

This is what I got. My connection setting is below. I can use VNC viewer to access my Firefox docker. So I believe I may miss some setting in Guacamole.

I tried to setup guacamole to VNC to firefox. However, I got a lot of java error in catalina.out. I totally follow the guidance from this source https://technicalramblings.com/blog/remotely-accessing-the-unraid-gui-with-guacamole-and-vnc-web-browser/ . It used to work before. Here is catalina.out log INFO: Server startup in 4384 ms 10:10:13.569 [http-nio-8080-exec-9] INFO o.a.g.r.auth.AuthenticationService - User "guacadmin" successfully authenticated from 192.168.10.33. 10:10:14.134 [http-nio-8080-exec-6] ERROR o.a.g.w.GuacamoleWebSocketTunnelEndpoint - Creation of WebSocket tunnel to guacd failed: Non-numeric character in element length. 10:10:14.260 [http-nio-8080-exec-10] ERROR o.a.g.s.GuacamoleHTTPTunnelServlet - HTTP tunnel request failed: Non-numeric character in element length. 10:10:15.329 [http-nio-8080-exec-7] ERROR o.a.g.w.GuacamoleWebSocketTunnelEndpoint - Creation of WebSocket tunnel to guacd failed: Non-numeric character in element length. 10:10:15.380 [http-nio-8080-exec-8] ERROR o.a.g.s.GuacamoleHTTPTunnelServlet - HTTP tunnel request failed: Non-numeric character in element length. 10:10:15.947 [http-nio-8080-exec-3] ERROR o.a.g.w.GuacamoleWebSocketTunnelEndpoint - Creation of WebSocket tunnel to guacd failed: Non-numeric character in element length. 10:10:16.040 [http-nio-8080-exec-6] ERROR o.a.g.s.GuacamoleHTTPTunnelServlet - HTTP tunnel request failed: Non-numeric character in element length. 10:10:16.366 [http-nio-8080-exec-4] ERROR o.a.g.w.GuacamoleWebSocketTunnelEndpoint - Creation of WebSocket tunnel to guacd failed: Non-numeric character in element length. Here is docker log
