hi,

how are you connecting to your server?
you need to be able to access port 3128 for spice to work
 
Connecting from windows with Remote viever program. Connecting with cfg which one downloaded from proxmox >console>spice.
Tryed to connect spice://192.168.31.221:3128 same error.

Click to expand...
is the port 3128 on your server accessible from your client?
if you have firewall set up on your PVE then you will have to allow that port from your IP
 
Be aware that the file you get when you open a spice console from the PVE GUI, is only valid for a short time (10 seconds or so). After that you need to download a new one.
 
Disabled firewall pve-firewall stop , same error. Tried on other pc with windows connect same error, so its no my windows pc firewall , av problems.
 
can you check with nmap if the port is really open? nmap your.pve.ip.here -p3128 -vv -Pn -n
 
I have the same problem with Spice.
nmap gives me the following output:
Code: 
nmap 172.27.11.22 -p3128 -vv -Pn -n

I have installed Remote Viewer 9.0-256 (64-bit).
This problem happens with a Proxmox 6.3-3 installation. I have another environment that is still running version 5.4-13. I can connect to a Linux desktop with Spice without any problems.

I did:
deleted
  • /etc/pve/pve-root-ca.pem
  • /etc/pve/priv/pve-root-ca.key
pvecm updatecerts -f
restarted proxmox, but same problem connecting over spice. Seeing new certificates, but maybe I am doing something wrong ?
