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 - Mike On Sat, Oct 29, 2022 at 8:05 AM Rytis <[email protected]> wrote: > Hi Nick, > thank you for quick response. > > guacd is running > root@orangepi:/var/log# systemctl status guacd > ● guacd.service - Guacamole Server > Loaded: loaded (/etc/systemd/system/guacd.service; enabled; vendor > preset: enabled) > Active: active (running) since Sat 2022-10-29 14:38:00 UTC; 25min ago > Docs: man:guacd(8) > Main PID: 5948 (guacd) > Tasks: 1 (limit: 4603) > Memory: 9.8M > CPU: 45ms > CGroup: /system.slice/guacd.service > └─5948 /usr/local/sbin/guacd -f > > 2022-10-29, št, 18:00 Nick Couchman <[email protected]> rašė: > >> On Sat, Oct 29, 2022 at 10:50 AM Rytis <[email protected]> wrote: >> > >> > 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.
