Netplan doesn't work with DHCP DNS server

[Pat]

Network/hardware setup:
pihole running on pi4 with local dns entries. Ex. somehost 192.168.1.10
udm pro configured with a manual dhcp name server giving the pihole's ip address
fresh install ubuntu server on a VMware ESXi host using dhcp

Problem:
from the ubuntu server "ping somehost" and "nslookup somehost" are both unable to resolve the local ip from the pihole. this functionality works fine from both windows and osx

"systemd-resolve --status" shows the correct pihole ip address in "Current DNS Server" and "DNS Servers" for the network interface
