Forgive my ignorant first post.. but I hadn't seen anything posted on this anywhere yet..
But we use a sharded Guac container config (w/external ha-proxy https front end) running at large scale (thousands of AWS VMs).. and since upgrading to v1.2, (preparing to upgrade to 1.3), but users are currently seeing dropped RDP sessions (multiple times/day) on both Windows(10, server 2016) as well as Linux (Ubuntu/Deb run xrdp). It physically looks like this: https://photos.app.goo.gl/zo165UeDtQHoYWST6 and in the logs: 17:22:47.909 [Thread-271] ERROR o.a.g.w.GuacamoleWebSocketTunnelEndpoint - Connection to guacd terminated abnormally: Connection to guacd timed out. ... 17:22:47.910 [Thread-271] INFO o.a.g.tunnel.TunnelRequestService - User "f1bb5985-5f0a-4ce5-8d25-ac031d198c97" disconnected from connection "a609c1f6-0b59-48e0-84eb-7850b62a6ddb/b7202e69-a7eb-4a68-8762-b60ca0815d68/2d5a891b-f7e7-4d99-b583-05376e5a2f5a". Duration: 311400 milliseconds Reconnecting (same session token) seems to work. Anyone seen this or know if it's related to a known issue? Never happened on older guac (v 0.95) -- T.Weeks VirginiaCyberRange.org
