IPv6 address cannot be blank for CR providing IPv4 plus domain with forward DNS

When creating a host (using EC2) it insists that the ipv6 address must be filled in.
This is preventing us from building new hosts, as we have no ipv6 support. (Even if ::1 is used, it fails when trying to add the DNS records.)
There are no ipv6 subnets configured and retrying with the blank address results in the same error.

What is the value of
token_duration in Settings? If zero, try specifying a non-zero value (the default).
Edit: actually, that may not be the issue - if a domain with forward DNS is configured, it would probably trigger the same condition, requiring an IPv6 address.
I think #17071 may contain a fix for this, it improves how IP address validations are skipped when a compute resource provides one of the IPs (e.g. it'd properly skip IPv6 address validation when EC2 provides an IPv4 address).

Is a domain set on the interface with a forward DNS proxy set? (I assume so, since you mention DNS in passing.)
Yes. We're doing forward/reverse management in ipv4 (with freeipa, which for this purpose can be treated as bind9 with a bunch of wrappers)

Proxy logs (1.11.4-1) show:
You should definitely update your smart proxy to 1.13. Smart Proxy 1.11 is not fully compatible with Foreman 1.13.
As a temporary workaround, you can replace this (in /usr/share/foreman/app/models/nic/base.rb) with "return false"
Dominic, I'll send a pr with a patch so that we can include a fix in 1.13.2 . #17071 seems a little to big to backport.

That replacement worked.
Great, would you mind testing the actual patch for this?
wget -O /tmp/17187.patch https://github.com/theforeman/foreman/pull/3988.patch
patch -p1 < /tmp/17187.patch
systemctl restart httpd.service
patch will be unable to find the unit test file, you can safely skip this patch.
Of course, you'll need to revert the hotfix first.
