I think that was it. I had the IP and port under Network on the first connection, and had the IP and port under GUACD on the other. Looks OK when I just corrected it and re-tested.

Let me describe how I have things set up, and hopefully its just something that I overlooked. 1) I made a new group called VNC. Its type is “Balancing”, and I set the max # of connections to 10 and the max per user to 2. I did not check “Enable Session Affinity”. 2) Under that group, I made 2 VNC connections. They both have the same IP address, but the first connection has port 5901 and second has port 5902. 3) I assign the VNC group to a user and have them try it. When the user clicks on VNC in their available connections list, they get an error stating that there was an internal Guacamole error. /var/log/messages shows the following: ERROR: o.a.g.s.GuacamoleHTTPTunnelServlet: HTTP tunnel request failed: Non-numeric character in element length I know it's simple and may sound silly, but can you double-check that when you put the VNC server and port number into the connections that you put it in the VNC connection properties and *not* in the box for the Guacamole server and port number? There's been some discussion that the location of the Guacamole server/port configuration boxes are placed in a slightly-unfortunate place where people often enter the target server information in the wrong place. -Nick
