Having difficults with dig in "Friendzone" (A lot of spoilers)


I’m doing Friendzone and I am having an issue finding the subdomains. I read some writeups and I think I did all the steps correctly but I get no subdomain.

I added my /etc/hosts file to:
FriendZone_IP friendzone.red friendzoneportal.red

I dig the dig with zone transfer
dig @My_VPN_IP friendzone.red
dig @My_VPN_IP friendzoneportal.red

On both these commands I get “Cpnnection to for domain failed: connection refused”

Is there anything that I am missing here?

Kind regards,
