Guacamole Error: guacd was inactive for too long

[vnydev]

Guacamole-lite and Guacamole-common-js Tunnel connection issue.

I am also facing the same issue ( Closing connection with error: Error: guacd was inactive for too long) . while connecting through WebSocket tunnel on the client side of application using Guacamole-common-js. I am exposing the WS endpoint using Guacamole -lite from Node-JS backend and trying to established the connection between client and WS so i can show the connected guacamole in side the web-application into the browsers.

Basically our requirement is to render the desktop applications of the user on the browser for that we are trying Guacamole RDP/SSH/VNC connection and want to display the respective connected remote server on the browsers to access desktop application.

Please help us its urgent.

You may want to check the port of your websocket connection. Normally, 4822 is the port the guacd daemon listens on, not the port on which guacamole-lite accepts the websocket connection, I believe.
