Oh, it appeared from the report that an IPv6 address in the interface
was not working.

Right, per the documentation for interface:
----------------------------8< cut here >8------------------------------
The first interface of the correct type (IPv4 or IPv6) is used for the outgoing
connection. If none of them are the correct type, the option is ignored.
----------------------------8< cut here >8------------------------------

Use something like (untested):
ignore_target_hosts = <; ::
on the Router to refuse to use IPv6 addresses. Or there's
dns_ipv4_lookup as a global option, per "13.6 Disabling IPv6".
