VNC for Instance opens Untitled page (25.04)

Apps and Virtualization

I just upgraded to 25.04 - all went smoothly, including the recreation of my HAOS VM by importing (moving) the zvol. Gave it 1 core and 4GB RAM, and macvlan over br0. All works OK (except it can no longer connect to my TrueNAS SMB share as external storage - but that may be a HA problem).

EDIT: I can now connect to the TrueNAS host. Had to remove macvlan and just use br0 as the attached NIC, as per Cannot ping TrueNAS Host from within Incus VM - #6 by Iridaen

The main question is that I can’t get VNC working. I’ve enabled it and left it on the default port (5900). However, when click the VNC’s address under “Details for haos > Tools” i.e. “vnc://mytruenas.com:5900”, it opens an Untitled tab in my browser, but nothing shows. I’ve tried the LAN IP address of my TrueNAS server too, but same result.

Do I need to add a GPU device to my Instance (I have a 1060 I can use)?

This is telling your browser to open a vnc session in your preferred VNC client. If you don’t have one defined or your browser is finicky, it may not be able to do that. I had trouble with this using Chrome on Windows–it worked fine on Linux.

You can still use your VNC client to connect to mytruenas.com:5900 (IP:PORT) manually.

Thanks DjP-iX - I think my brain is getting full - shoulda been able to figure that one out!
