[SOLVED] Cant access proxmox webgui

I need to re-awake this thread!

I figured out to make my DC safer and add SSL cert for trusted https that is only accessible from LAN, with 2FA etc...

however when pvenode acme cert order -f
Code:
Can't use an undefined value as a HASH reference at /usr/share/perl5/PVE/API2/ACME.pm line 196.

I never messed with certs before, this is first time and I just followed the steps of https://pve.proxmox.com/wiki/Certificate_Management
and yeah... it stops at pvenode acme cert order...

I tried following the solution for lps90 but I have no file at etc/default/pveproxy, doesn't exist.

So... I am at loss... what should I do?
