Your named is clearly not transferring to, but you apparently did
not move the ns2 to new IP so it still tries to fetch zone(s) from old IP.
Move ns2 to and it will ask fot transfers from that IP.

allow-transfer only configures who (which IP) will be allowed to transfer
a zone, but it has nothing to do with who will ask to fetch the zone.
