Hi Team, Thank you for your response.
We will review the suggested areas and investigate further to identify the possible root cause of the issue. For your reference, we are currently using the following setup: - *Guacamole Version:* 1.5.5 - *Guacd Version:* 1.5.5 - *VNC Server:* x11vnc We appreciate your support and will get back to you with any additional findings or clarifications if needed.
