Empty/black console with LXC "tty"

[Hitnerte]

Hello,
I created an LXC container with the "debian-11-standard_11.3-1_amd64.tar.zst" template.
When I'm trying to access the console it's empty. I can't do anything with it. I have to switch the "Console mode" to "shell" to make it work.
What can cause this? I tried to press enter or any other keys but it does not work.

Version:
pve-manager/7.2-5/12f1e639 (running kernel: 5.15.39-1-pve)

can you post the complete container config? (pct config ID) ?

With Ubuntu (ubuntu-22.04-standard_22.04-1_amd64.tar.zst) it seems to work well.

ip6=dhcp

do you have an ip6 dhcp server? if not, the container may wait with the starting until a timeout (most often 5minutes) is complete before it's started completely

Thanks, that was the problem.

@dcsapak: That was my problem too. Thanks, the tip helped.
