Unable to get Guacmole to connect to hosts
Hello,
I am trying to install Apache Guacamole on RHEL 8.
I've followed all of the instructions linked below:
https://computingforgeeks.com/install-guacamole-remote-desktop-centos/
I've gotten to the point where Guacamole is loading and I'm able to sign in. The problem I'm having, however, is that whenever I try to connect to a host, I am getting the following error message:
[cid:67388e98-f5e4-4cad-bcce-9a6554b54468]
"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".
The Guacamole documentation says to check the syslogs. I've checked /var/log/messages and I'm not seeing anything related to the error.
Any help to troubleshoot would be much appreciated.
Regards,
Timothy Dilbert

Thank you, Ivanmarus. I'm sorry for not responding earlier. These responses ended up in my junk mail.
I ended up switching over to Ubuntu which was a lot easier to deploy Guacamole on. When I get OpenShift up and running I will research switching over to a container, thus back to RHEL.

Timothy,
I had a quick look at that site. While I can't comment much on the
procedure for RHEL (I generally use Ubuntu) I see they appear to be
advising an earlier version of Guacamole than is current.
I suggest you check this out, it's the official documentation for the
current version (1.4), and includes information relating to RHEL:
https://guacamole.apache.org/doc/1.4.0/gug/installing-guacamole.html
Hopefully that will help. If you remain stuck I did post a step-by-step
install for Ubuntu/Debian a while ago, it may give some pointers and is
visible in this thread:
https://lists.apache.org/thread/99qphjvmmfpwpm5y0h5hyxlzn3l0qbm1
Please let us know how you get on. Also, although I'm not familiar with
RHEL file locations etc, you may find there's a 'catalina.out' logfile
that could contain further information?

For testing disable SELinux and reboot the server.
Verify it up and running use the following command: sestatus or getenforce
Disable SELinux temporary use the following command: setenforce 0 If you are using sudo accounts put sudo in front of the commands
To Permanently disable vi /etc/selinux/config then set SELINUX= disabled save and reboot
The idea here is to eliminate potential blocks.
Next I would check the firewall making sure the ports are open.
Thank You
