I said it was dns.

The join is supposed to find the best DC to use during the join and it
looks like your new DC couldn't find a DC to join to. Using '--server'
tells the join to use that DC, so the question has to be, did your
/etc/resolv.conf look like this:

nameserver <AN_AD_DC_IP>

Does your new DC have a fixed IP ?
Is its IP info in /etc/hosts ?

Have you updated your new DC's /etc/resolv.conf to now use its
ipaddress as its nameserver ?
