Presumably because the dhcpv6 protocol didn't finish? Journalctl output below.

Ouch. Please try to set UseAddress=no in [DHCPv6] section as a workaround.

network: do not request DHCP addresses configured on checking prefix …
b7bc590 
…delegation

This does not change anything for DHCPv4, as a DHCPv4 address is always
requested anyway. However for DHCPv6, the client may not request IA_NA
addresses by UseAddress=no, or even if it is requested, the server may
not provide any IA_NA addresses. Even in such cases, here the check is
for delegated prefixes, hence it is not necessary to check if DHCPv6
IA_NA addresses are configured.
