When i open the console (web gui) it throws this error:
failed waiting for client: failed to lookup address information: Name or service not known
TASK ERROR: command '/usr/bin/termproxy 5901 --path /vms/101 --perm VM.Console -- /usr/bin/dtach -A /var/run/dtach/vzctlconsole101 -r winch -z lxc-console -n 101 -e -1' failed: exit code 1

my /etc/hosts:
\127.0.0.1 localhost.localdomain localhost
192.168.88.161 pmox.mydomain.org local

# The following lines are desirable for IPv6 capable hosts

::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

curl -k https://127.0.0.1:8006 puts out:

Hi Viper_Prime,

I don't think I can help you, but I can show what it is on my side. Do you mean the integrated web-console,

or the popup NoVNC/xterm.js

On my systems I don't rely on them, sometimes they don't give output for me and when they do, the functionality is hindered by it not being in a regular terminal (eg, I recall trouble copy/paste, and slow response).

For your benefit, when I curl the page on PVE9, it looks a lot like your output:

That looks a bit suspicious. Did you copy/paste, or type manually? The '/' can't be good there, and 'local' can be a hostname, but if it is not confusing Debian, at least it's confusing me (having expected 'prox' like in the FQDN)

Good luck!
