But RDP is working for IPV4, not working for IPV6. We are seeing the below error messages. Can you please let me know if any configuration changes are required to make RDP works? guacamole pod logs: Exception in thread "Thread-11" java.lang.IllegalStateException: Message will not be sent because the WebSocket session has been closed at org.apache.tomcat.websocket.WsRemoteEndpointImplBase.writeMessagePart(WsRemoteEndpointImplBase.java:442) at org.apache.tomcat.websocket.WsRemoteEndpointImplBase.sendMessageBlock(WsRemoteEndpointImplBase.java:314) at org.apache.tomcat.websocket.WsRemoteEndpointImplBase.sendMessageBlock(WsRemoteEndpointImplBase.java:254) at org.apache.tomcat.websocket.WsRemoteEndpointImplBase.sendString(WsRemoteEndpointImplBase.java:195) guacd pod logs: guacd[273]: INFO: User "@18ba0780-231a-47dc-bd1c-2c82c11a9661" joined connection "$afb33334-6b69-448c-9432-348c70dd49f1" (1 users now present) guacd[273]: INFO: Recording of session will be saved to "/home/guacd/recordings/2a00:fbc:1310:1835:9078:c343:517e:72942a00:fbc:1310:1835:9078:c343:517e:7294_rdp_recording.2". guacd[273]: INFO: Loading keymap "base" guacd[273]: INFO: Loading keymap "en-us-qwerty" guacd[273]: INFO: RDP server closed/refused connection: DNS lookup failed (incorrect hostname?) guacd[273]: INFO: User "@18ba0780-231a-47dc-bd1c-2c82c11a9661" disconnected (0 users remain) guacd[273]: INFO: Last user of connection "$afb33334-6b69-448c-9432-348c70dd49f1" disconnected guacd[6]: INFO: Connection "$afb33334-6b69-448c-9432-348c70dd49f1" removed.
