Installing n8n

[WangTiankunKenny]

at very first, we tried to use the script as it mentioned to install n8m, and as it went, we realized that we are in different region that could not get "google" then we start to use proxychain within our proxy server, at very begining, it words fine, but when it runs into whiptail, any of the "spacebar" and "go" does not work.
Here is the error
[ERROR] in line 799: exit code 0: while executing command CHOICE=$(whiptail --backtitle "Proxmox VE Helper Scripts" --title "SETTINGS" --menu "Choose an option:" 18 60 6 "1" "Default Settings" "2" "Default Settings (with verbose)" "3" "Advanced Settings" "4" "Use Config File" "5" "Diagnostic Settings" "6" "Exit" --nocancel --default-item "1" 3>&1 1>&2 2>&3)

dont know if you guys could understand me, sorry for my poor enlish.

I've checked whiptail works fine, proxy server works too.
