To provide a little more detail, when I’m using external DHCP the client hangs during cloud-init before enlistment happens, as I see no new data showing up in /var/snap/maas/common/log/rsyslog/maas-enlisting-node/$ip_addr like I do when I have MAAS DHCP management enabled.
In comparing my client where DHCP is MAAS-managed vs. not I see in /var/snap/maas/common/log/httpd/access.log this when it’s working:

But I see this when it’s not working:

One thing I’ve noticed in enlistment logs where clients are working is that cloud-init reports handing out an IPv6 address to clients. I don’t currently provide IPv6 addresses via my external server, but I’m not sure if this is relevant or related to the failures I’m seeing.
