[FEATURE] Add VNC TLS encryption support

Title

Add an option to select VNC encryption mode (None / TLS / VeNCrypt) in the VNC connection settings

Platform

Web-app

Is it related to an issue?

Termix VNC connections do not support TLS encryption, making it incompatible with VNC servers that require it (e.g. wayvnc with enable_auth=true)

The server logs show 404 error on /metrics/... as soon as I try to connect.

10.1.100.12 - - [11/Apr/2026:08:09:27 +0200] "GET /metrics/8 HTTP/1.1" 404 433

Steps to reproduce:

1. Set up wayvnc with TLS enabled in /etc/wayvnc/config
2. Add the host in Termix as a VNC connection
3. Attempt to connect — fails with /metrics 404 errors

Workaround:
My workaround was to disable TLS on the VNC server side. See image below.
Once I restarted the VNC server on the Raspberry PI. I was able to connect from Termix successfully.

Environment:

• Termix version: 2.0.0
• VNC server: wayvnc
• OS where VNC Server is running: Raspberry Pi OS (Debian GNU/Linux 12 (bookworm))

The Solution

An option to select VNC encryption mode (None / TLS / VeNCrypt) in the VNC connection settings.

Additional Context

I should also add that I am running Termix from a Proxmox LXC.
