Hello everyone!

I recently upgraded from pve 6 to 7 and moved my cluster to a new network. Unfortunately the remote vnc console is broken now.


I cannot access the "Console" of a VM from one node if the VM is not running locally. If the VM is running on the same node, the vnc connection works perfectly fine. LXC container _can_ be managed both locally and remotely perfectly fine. Only VNC cannot be used remotely. The Task error with:

Code: 
LC_PVE_TICKET not set, VNC proxy without password is forbidden
TASK ERROR: Failed to run vncproxy.


What I already did:
  1. Double checkt that the network config on all nodes is correct
  2. I recreated the self-signed certificate and restarted all the pveproxyies
  3. I removed the know-hosts files from all my nodes, symlinked the `/etc/pve/priv/known_hosts` to `/root/.ssh/known_hosts` and made sure that each server can access each other server via ssh
  4. I tried the suggestion from the forum posts here (Even though my problem is most likely not related) -> https://forum.proxmox.com/threads/task-error-failed-to-run-vncproxy.49954/ -> I get the same error as in the web-interface with the cli command:

Any suggestions how to fix this problem? Thanks in advance!

on a hunch - did you modify the sshd_config? (most importantly does it contain the line: `AcceptEnv LANG LC_*`?

I hope this helps!

Sorry to (re-)activate this thread, but i am also facing this issue.
As to the above provided solution i am a bit cautioned by introducing wildcards.
My situation :
- LXC console (across the cluster) works fine.
- VM console only works when i am on the GUI of the node the VM is on.
- certificates are distributed accordingly / via Ansible.
- No changes were/are introduced as to sshd_config
- default configured is
Code: 
# Accept locale-related environment variables
AcceptEnv LANG LC_CTYPE LC_NUMERIC LC_TIME LC_COLLATE LC_MONETARY LC_MESSAGES
AcceptEnv LC_PAPER LC_NAME LC_ADDRESS LC_TELEPHONE LC_MEASUREMENT
AcceptEnv LC_IDENTIFICATION LC_ALL
in /etc/ssh/sshd_config

- Tried adding
Code: 
AcceptEnv LANG LC_PVE_TICKET
on all nodes
=> has not changed behaviour.

So what is more needed (tailored to just this) to get rid of the 'error' ?

After fighting against this problem too, you also need to change the config on the client side (the server from where you are requesting the VNC console) :

For the client (/etc/ssh/ssh_config)
Code: 
SendEnv LC_PVE_TICKET

For the server (/etc/ssh/sshd_config)
Code: 
AcceptEnv LC_PVE_TICKET

What do you mean by 'the server from where you are requesting the VNC console'?
I am using the browser with my Laptop.

This is really ugly stuff. We are not able to fix that and all our admins can not use the web console for now.

This problem only happens when you try to access a VM Spice console from a different server than the one hosting the VM.

Client = the proxmox server you're using to access the web management interface (eg : proxmox1.local)
Server = the proxmox server where your VM is living (eg : proxmox2.local)

With single host setups, it's working fine out of the box. But in case of clusters, it's a different story.
What kind of setup are you using for your proxmox hosts ?
 
For future reference, if anyone find this thread:
I had the same issue and couldn't figure the culprit for more than a month.
For me the problem was a missing ssh_config file in /etc/ssh (note that this is the client config file, and not the server one).
I just copied over the file from another node and solved the issue.
 
I have the same problem ,I don't konw how to solve It.
I update my openssh to 9.6p1,and the sshd_config have AcceptEnv LANG LC_*,the ssh_config have SendEnv LANG LC_* too.
I also try input pvecm updatecerts ,but it's doesn't work too.

anybody can help me?

Thank you very much.
