Missing console on CTs

[Tealk]

Hi,

I have recently set up a new PVE server and the problem with the CT's is that I get no output the second time I call up the console. Only when I restart PVE can I see something again, but only the first time I call up a CT console.
I have use the debian-12-standard_12.7-1_amd64.tar.zst Template.

Try typing ENTER into the console. Usually this happens when the log in prompt does not get properly redrawn, sending ENTER to the container should trigger that.

Thank you that helps <3

Your CT might also be hanging there because of a network misconfiguration. Enabling DHCPv6 has often been a cause in the past.

For more debugging info, set lxc Options / Console mode to /dev/console

You can still get into it with ' pct enter vmid ' from ssh / Proxmox console

Glad to hear that. You could try to debug this further, but to be honest, this is somewhat expected. You can mark this thread as “solved” by clicking the “Edit Thread” button on top and selecting the “Solved” prefix. This helps other user with the same problem find a solution. Thanks!

Ok that doesn't always help, I can even write text in the console without the host reacting.

It really does seem to be related to IPv6 being set to DHCP.
