Guacamole can't connect to anything, no errors
Hello,
I am stuck for awhile with Guacamole - I have installed it using this
guide: https://idroot.us/install-apache-guacamole-debian-11/ (using Orange
Pi, Debian 11 (arm64)).
Guacamole application works well and I can login to it, but I can't connect
to any server (does not matter - ssh, rdp, application provides instant "An
internal error has occurred within the Guacamole server, and the connection
has been terminated. If the problem persists, please notify your system
administrator, or check your system logs.").
/var/log/syslog provides no guacd, tomcat9 errors or anything else related
to this.
I am quite stuck here. Is there any other way to identify a problem?
Thank you,

Best regards

Thank you, Michael -
forceing guacd to listen on 127.0.0.1 actually worked!

Look around to see if you can find your Tomcat logs. The location of the
Tomcat logs varies by how Tomcat was installed and by who created the
Tomcat package. There should definitely be an error in the logs that
corresponds to the error you're seeing in the UI. Common locations would be
within the systemd journal (accessed via journalctl) or "catalina.out"
beneath a directory within /var/log, such as /var/log/tomcat or
/var/log/tomcat/9 or similar.
I suspect that your system may have configured the "localhost" name such
that guacd is binding to IPv6 localhost, while the Guacamole webapp is
attempting to connect to IPv4 localhost. If this is the case, you can force
guacd to listen on 127.0.0.1 by editing /etc/guacamole/guacd.conf, creating
the file first if necessary:
[server]
bind_host = 127.0.0.1
See:
https://guacamole.apache.org/doc/gug/configuring-guacamole.html?highlight=bind_host#configuring-guacd

Is guacd running? I'm unfamiliar with that install guide you
mentioned, but have you started the guacd service, either using
systemctl, an init script, or by running the guacd binary directly?

Check to see if the guacd service is actually running.
I had a similar issue with a new installation very recently.
Kind regards,
