Subject Problem guacd timed out.
Date Mon, 06 Feb 2017 12:08:53 GMT
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.



Output of /var/log/syslog:
