Hi,

netstat -ltn | grep 8006
tcp6 0 0 :::8006 :::* LISTEN

are you using IPv6?

what says the output of the command below?

curl -k https://localhost:8006 | grep title

Hello Moayad,

I have the same issue with the same issue for me its fresh install. it seems proxmox is using tcp6 instead of tcp. Any suggestion what should i check this if fresh install.
