Hi gongomgra,
Guacamole OVA is running in a production vmware vsphere 6.7 with many windows server on the same network.
Network and access to rdp in windows works well from many different networks.
Guacamole I like to used for centralized access.
The pictures show what happen. Logon to system. Open device manager, work. Open task manager or "start" disconnect system and after that not connect again.
Only log with some info is
/opt/bitnami/guacamole-server/logs/guacd.log
