When a mid-path middlebox silently drops the TCP between the browser and HAProxy, HAProxy closes the backend which rustguac logs as "Connection reset without closing handshake" (termination state CD-- in HAProxy's log). Firefox's WS socket then fires onclose on the browser side, Tunnel.js's close_tunnel() runs, and the tunnel's internal state transitions to CLOSED. But upstream Guacamole's Client.js doesn't listen for tunnel.onerror or tunnel.onstatechange — the Apache webapp's AngularJS wiring does that externally. Our lean client.html inherited Tunnel.js + Client.js verbatim from upstream but missed that glue, so tunnel errors fired into the void and the Guacamole client stayed in CONNECTED forever. Effect on users: a dead session that looks like a freeze. Mouse moves locally, clicks don't register (they're being sent into a closed WebSocket whose send() silently no-ops at the browser layer). The "Session Ended" overlay never appears. Meanwhile the thumbnail uploader keeps running on its own XHR stream, getting 404s from the already-cleaned-up session. Fix: wire tunnel.onerror to forward into the existing client.onerror handler, and wire tunnel.onstatechange so CLOSED also triggers the overlay (and UNSTABLE updates the status text). This reuses the existing overlay wiring at client.html:895; no new UI, no new state machine, no new heartbeat. The upstream-inherited 5s nop keepalive and 15s receiveTimeout in Tunnel.js are already present and correct — the missing piece was just propagating their output into the client's state cascade. Triggered a lot of detective work chasing false leads (H.264 decoder closed-state hypothesis, h2 bridging bug, HAProxy timeout tuning, client/server heartbeats). The actual cause was much simpler and the diff is six lines of JavaScript.
