I am using Ubuntu 16.04.4 LTS and follows the guideline here to install the guacamole : https://guacamole.apache.org/doc/gug/installing-guacamole.html#building-guacamole-server
During the installation, all requirements are met and installed successfully. And I found that when i try to login, it fails to do so and the logs below appears: at /var/log/syslog Protocol "vnc" selected Error loading client plugin: Invalid argument at tomcat7 catalina.out ERROR o.a.g.s.GuacamoleHTTPTunnelServlent - HTTP Tunnel request failed: End of stream while waiting for "args" Any hint on this issue? Thanks very much! -- Sent from: http://apache-guacamole-general-user-mailing-list.2363388.n4.nabble.com/
