Hi, I made a new install of Ubuntu 16.04.1 LTS and Guacamole 0.9.11-incubating released on February 3rd.
Since the last version, I have occasionally had trouble connecting to some servers at random. An example is as we can see below. I clicked to connect to a server and it stays in this screen: [image: Imagem inline 1] After a while this screen appears: [image: Imagem inline 2] If I click on "reconnect" the connection will go normally. But if I wait a few minutes and try to reconnect to the same server, the same problems happen again. Below is the output of the guacd log in debug mode and tomcat8. I'm just using tomcat8, with mysql. Apache or nginx is not installed.
