Proxying Guacamole through Nginx doesn't get rid of Tomcat, it simply puts Tomcat behind Nginx, so that Nginx can provide HTTPS access and a more standard port than Tomcat, in a more secure fashion than Java. Nginx is also easier to configure SSL/TLS on than Tomcat. > I have install the setup guacamole 1.0+tomcat 8 +xrdp in one machine and > this machine is accessible over WAN .

These messages indicate that Guacamole-related traffic is not making it from the client machine (web browser) to guacd. This can indicate any number of problems, including misconfiguration, resource issues, or other software that interferes with the communication (e.g. application-aware firewalls, also known as deep-packet inspection). If you only see this issue when you're using Nginx as a proxy, then verify, first, that you've configured Nginx as directed in the manual - most notably, there are some parameters related to buffering that absolutely must be present in order to make the connections stable. If you've configured Nginx correctly, then I would look next for network-related items, like firewalls that are inspecting HTTPS traffic, and make sure that those are not interfering. If you've verified configuration and network, then look at the components of Guacamole and make sure there are not any resource constraints - CPU, RAM, or network bandwidth. -Nick
