Cloudflare Dynamic DNS API broke in update

[republicus]

I preformed an upgrade and now my Dynamic DNS settings for Cloudflare fail.

Ive reverted back and it works again.

I have two systems with the same symptoms.
(1) OPNsense 18.1.13_1-amd64 -- Cloudflare works until updated
(2) Clean install using OPNsense-18.7-OpenSSL-dvd-amd64.iso -- Cloudflare works until updated

Cached IP shows 0.0.0.0 and does not update.
When researching the problem I only find old mentions at pfsense from years ago

Any thoughts?
