[Proxmox : Console] Can't access to to console from proxmox

[PanaceaMan]

Hello all !

This morning, i wanted access to a console of a VM but this error appears :

no connection : Connection timed out
TASK ERROR: command '/bin/nc -l -p 5900 -w 10 -c '/usr/sbin/qm vncproxy 106 2>/dev/null'' failed: exit code 1

So i tried another one and it was the same problem...
What it may come ? How can i resolve this problem without reboot proxmox ?

Many thanks in advance for your help !

Hello snowman66 !
Thanks for your quick reply !

I've tried with the latest Firefox, Google Chrome and Internet explorer but with no success.
I don't think the problem come from the web browser because the error is : command '/bin/nc -l -p 5900 -w 10 -c '/usr/sbin/qm vncproxy 106 2>/dev/null'' failed: exit code 1
It's looks like a internal error of proxmox.

Any hint in /var/log/syslog? The VM is running?

Hi dietmar ! Thanks for your reply !

All VM that i've tried to view console are running.

In syslog, i've got no information that could help me :

May 14 08:44:32 proxmox1 pvedaemon[541263]: <root@pam> successful auth for user 'admin@pve'
May 14 08:44:42 proxmox1 pvedaemon[544020]: command '/bin/nc -l -p 5900 -w 10 -c '/usr/sbin/qm vncproxy 106 2>/dev/null'' failed: exit code 1

and nothing interesting after

Do you run some kind of firewall?

There is no firewall that could block the console.
Something is strange because everything was working fine and the next day, the console was unreachable..

Does it help if you shutdown, then restart this VM?

Good idea but i think really there is a problem with the Console program of Proxmox.
Because all my VM can't be reachable with the Console program of promox.
I've tried your suggestion but i wasn't lucky :/
Is there a command line that it could restart this module ? (i don't really think there is a module named "console" and can be restarted separately)
I will try to restart apache and see what's happened.

EDIT : Nothing has changed with the restart of apache. Maybe java of my computer has a problem : i will remove it and reinstall it.

SUCCESS ! : It was Java ! Removing and reinstalling java has resolved this problem !
Thanks everyone for your help ! This error has really got me stuck !
