No RDP connection via Guacamole; Connection possible with Remote Desktop Client of Windows
I created 2 VM Machines on Azure:
1. Windows 10 Machine
2. Apache guacamole (Bitnami - the referred me to here, as they are unable
to help)
It is possible for me to connect to the Win10 machine with the remote
desktop client from my home laptop.
I configure the guacamole machine as following:
Protocoll: RDP
Hostname: corresponding public IP Adress of the Win Machine
Port: 3389
Username: xxx
Password: xxx
Securitymode: NLA (I tried every mode, none worked)
Ignore certificates: checked
The output of the syslog is as following (last two login attempts) :

It's not created by default, at least in native Guacamole installs, so you
might have to generate it yourself. It should be in /etc/guacamole/ and
called guacd.conf.

Ah, interesting. This still doesn't look like debug mode - could you try
starting in debug mode and see what happens? Also, it occurs to me if
you're using Guacamole 1.3 and encountering this issue that it could be
related to the caches that FreeRDP doesn't support and that we've forcibly
disabled in 1.4. You might try making sure that the Glyphy Caching, in
particular, is disabled, and see if that helps.

Hey Nick,
I'm honestly trying my best!
I'm not able to start guacd in debug mode, because Bitnami wont let me. I
can stop the process via sudo /opt/bitnami/ctlscript.sh stop but as I try
to star it with sudo /opt/bitnami/ctlscript.sh start guacd -L debug it
says: Failed to start guacd: [guacd] Other action already in progress --
please try again later
I tried to find the guacd.conf, however it seems that Bitnami puts that
file somewhere else.
Next step: I installed locate with sudo apt-get install locate, but when I
use locate guacd.conf nothing happens.
However as i recently checked the log, a new line appeared, maybe this
helps (*bold*)

I hope I get closer to the problem.

That's interesting - as the project doesn't officially produce the Bitnami
containers it would be difficult for us to support them any better than
Bitnami. But we can certainly try!

You might want to start guacd in debug mode and see if it gives any more
useful information. This can be done by started guacd with the "-L debug"
flag, or changing the log level in the guacd.conf file.
