You need to check syslog - either /var/log/messages, journalctl, or
wherever syslog messages are normally logged on your system.  guacd output
will be there.

Hi Guillermo,

My suggestion would be to also check the logs of the company firewall,
if you have one.
I've seen some cases in which remote desktop software can trigger
flooding protections that are implemented in such firewalls.

Guilherme,

I see in other posts you're using Ubuntu 18.04?

It may be worth checking what version of FreeRDP you're using (ldconfig 
-v | grep free). If it's 2.1.1 then you could be running into this problem:

http://apache-guacamole-general-user-mailing-list.2363388.n4.nabble.com/Guacamole-FreeRDP-disconnect-td8575.html

The reason for the problem, and fix/workaround, is included in that thread.

Are you using Ubuntu 18.04 for this Guacamole deployment? I had a similar
problem, along with huge memory consumption for every guacd process (more
than 1gb each), and the problem was with the freerdp libraries packaged in
Ubuntu 18.04. I reinstalled on Debian 10 and now it runs fine with more
than 200 simultaneous users (the server has 32 cores and 64gb ram).
