Hello! I've been running guacamole for years but just started to have this issue and I'm a little stumped. When I connect to a computer using my web browser, I get a "The connection has been closed because the server is taking too long to respond." error. As far as I can tell, nothing is wrong with the client machines, and it started doing this for all of them at the same time. I would love any help you could provide!
I have guacamole running in Docker. Looking at the logs, I can see guacd create and remove a connection pretty much instantaneously: guacd[1]: INFO: Creating new client for protocol "rdp" guacd[1]: INFO: Connection ID is "$8f71f593-2fc4-4a7c-8308-3e32c8e9cf1c" guacd[119]: INFO: Security mode: NLA guacd[119]: INFO: Resize method: none guacd[119]: INFO: No clipboard line-ending normalization specified.

On the guacamole side it tries to connect, then guacd removes the connection, and then 15s later guacamole times out the connection: 21:47:46.148 [http-nio-8080-exec-8] INFO o.a.g.tunnel.TunnelRequestService - User "guacadmin" connected to connection "3". 21:48:01.164 [Thread-7] ERROR o.a.g.w.GuacamoleWebSocketTunnelEndpoint - Connection to guacd terminated abnormally: Connection to guacd timed out. 21:48:01.165 [Thread-7] INFO o.a.g.tunnel.TunnelRequestService - User "guacadmin" disconnected from connection "3".
