unknown host

Hi, on my Proxmox host I cannot run pct list anymore because it's endless and I don't have any output: root@node11:~# pct list (no return to console...) If I try to run it with strace I get one endless timeout but I cannot realize which program is creating it: root@node11:~# strace pct list...

Hello, noob here, I've tried many of the solutions listed but can't figure it out. I'm installing proxmox onto an old dell optiplex I have connected to my shitty AT&T modem. I set the computer's ip to static and set the ip in proxmox when installing to the same ip (I left the rest to default)...
