console shows blank page

What
Console webpage for any instance is blank(I tried on a windows server and Debian without desktop env) as the screenshot below:
I didn't find any error message on the webpage.
System environment
System Info:
KVM is QEMU with KVM, connected via local.
The WebVirtCloud is installed by installer. Proxy by Nginx with the config in /srv/webvirtcloud/conf/nginx/webvirtcloud.conf
All services seem working well:
Would anyone please help on this issue, thanks.
I didn't find noVNC log file, if any log or additional information is required please let me know.
i think you are using spice for console. spice is deprecated by qemu/kvm + libvirt. can you please change console type spice to vnc, then try again.

Nope, I think it is vnc now..
your screenshot shows default settings. but you must change instance settings.
do you access instances on remote host or localhost?
Oh yes, now the instance was using spice and I changed it to vnc. But after this I got an error message on the console page: 'Something went wrong, connection is closed'
And I'm accessing localhost
after changing console spice to vnc, you must change also primary video model.(recommended one vga)
Set to VGA, but the error still. I paste the instance's xml config hope can be more clear:

it seems there is not a problem with instance config. (to make verification you can use virt-viewer)
it can be webvirtcloud settings. i tested with debian12 with using "install.sh" there is not any problem with console. my settings.py config like that
.
..
..........
#
# WebVirtCloud settings
#
# Websock port
WS_PORT = 6080
# Websock host
WS_HOST = '0.0.0.0'
# Websock public port - 80 or 443 if reverse-proxy, else 6080
WS_PUBLIC_PORT = 6080
# Websock public host
WS_PUBLIC_HOST = None
# Websock public path
WS_PUBLIC_PATH = "/novncd/"
# Websock Certificate for SSL
WS_CERT = None
SOCKETIO_PORT = 6081
SOCKETIO_HOST = '0.0.0.0'
# Socketio public host
SOCKETIO_PUBLIC_HOST = None
# Socketio public port - 80 or 443 if reverse-proxy, else 6081
SOCKETIO_PUBLIC_PORT = 6081
# Socketio public path
SOCKETIO_PUBLIC_PATH = "socket.io/"
# List of console listen addresses
QEMU_CONSOLE_LISTENER_ADDRESSES = (
("127.0.0.1", "Localhost"),
("0.0.0.0", "All interfaces"),
)
.................

Seems there is not much difference excepting I'm using reverse proxy so the public ports are 443..
settings.py:
Nginx config:
Hımm you are using https then you must use certificate with console
#173
This issue explains how to use it
Just tried but issue still. And I think my case is different with the one you pointed out. In #173 the ssl is handled by the noVNC service itself (on 6080 port), but for mine the ssl is handled by Nginx so for noVNC service self is not using ssl..
Do we have anyway to enable more debug log to identify what happened? For now only this is printed out:
