Can no longer access Server/VM/LXC's Shell/Console with Firefox

[rs_taylor]

HI,

Firstly, i've found several people with similiar issues, but most seem to be VERY old and seem to be related to using Clusters which im not.
I have a Single PC, running Proxmox VE 8.2.2, have been using it for about 6months, its runs several LXC's and a OPNSense virutal machine.

All containers are running their apps just fine & can be started and stopped from the Proxmox WebGUI.
I can maintain most of them via their own WebGUI's but occassionally i need to drop to a shell.
I used do this from the Proxmox WebGUI, selecting the node/container/app i wanted a shell for & right clicked and chose Console/Shell.

Recently (in the past couple of days) this has stopped working. Whether it be the Nodes themselves or the "pve" (i never renamed it).
I have always used Firefox but have discovered Bing works fine (gives me the shell/Console i want)

Examples of Output Error

failed waiting for client: timed out
TASK ERROR: command '/usr/bin/termproxy 5900 --path /vms/101 --perm VM.Console -- /usr/bin/dtach -A /var/run/dtach/vzctlconsole101 -r winch -z lxc-attach --clear-env -n 101' failed: exit code 1

failed waiting for client: timed out
TASK ERROR: command '/usr/bin/termproxy 5900 --path /nodes/pve --perm Sys.Console -- /bin/login -f root' failed: exit code 1

Any help greatly appreciated!

Hi,

Can you please check the `pct enter 101` of the LXC?

And did you see other above provided output in the syslog? you can run `journalctl -f` and try to access the LXC Console in the Proxmox VE Web UI.

I cant(or couldn't) use the WebGUI to drop/shell to console at the parent level, but i can with SSH & i can use PCT Enter to access any of the running LXC's.

Should i run journalctl -f from the LXC or at the parent level?

I dont know if this "Fixed" it (if it did thank you!), but my console/shells are now opening as expected.

If you want to know what happened exactly and how fixed the issue, you can post more information for the syslog/journalctl!

 

[rs_taylor]

I dont know how to do that. i ran the journalctl -f and pasted in the output

Nope, no news. I'm using another browser for Proxmox as I also have keyboard problems under noVNC with Firefox.
