For example, if the load balancer doesn't see ongoing Websocket communication as activity, and is expecting HTTP(S) commands from the client-side, that may result in it timing out the connection. Or, if the connection is timing out after 30 seconds because the user is not doing anything (typing/moving mouse on client side), and the only traffic is coming from the server-side, then it may want to close the connection. Or it could be that the load balancer is seeing the repeated "NOP" commands that go back-and-forth between client and guacd and deciding that those represent a "keepalive" attempt by one end or the other, and is configured to ignore attempts to keep connections alive. You might dig into the load balancer configuration and see if there are other parameters that can be adjusted to tweak how it identifies idle connections, or just eliminate that functionality entirely for the Guacamole traffic. -Nick
Re: Guacamole server disconnect after 30 sec
Hi Daniel, You are right I changed the timeout for the load balancer to 2147483645 (INT MAX - by default it was 30 sec), and now the issue is fixed, but I still don't understand why this timeout on the load balancer was causing the issue.

Re: Guacamole server disconnect after 30 sec
Hi Anoop, Notice the following log line: [http-nio-8080-exec-17] INFO o.a.g.r.auth.AuthenticationService - User \"master_admin\" successfully authenticated from [122.x.x.x, 34.x.x.x, 35.x.x.x].", Multiple IPs are listed. That means that this connection is being proxied, twice. The odds are high that one of these proxies is terminating the connection after 30 seconds, and that's the source of this issue. One or both proxies will need to be reconfigured to support very long timeouts.

Guacamole server disconnect after 30 sec
I am running guacamole/guacd:1.5.4 and guacamole/guacamole:1.5.4 on Google Kubernetes, but I am facing an issue I can connect to the RDP connection for just 30 seconds after that it shows a notification *"The Guacamole server is not currently reachable.
