DuckDNS addon does not actually work with URL options

[ast0815]

Describe the issue you are experiencing

I want to use an URL to determine my IPv6 address, since duckdns cannot determine that itself. Unfortunately that does not seem to work.

What type of installation are you running?

Home Assistant OS

Which operating system are you running on?

Home Assistant Operating System

Which add-on are you reporting an issue with?

Duck DNS

What is the version of the add-on?

1.15.0

Steps to reproduce the issue

1. Setup Duck DNS and add-on
2. Check it works with updating the IPv4 address when providing no values for "IPv4" and "IPv6" config options
3. Set "IPv6" option to https://api6.ipify.org/
4. It no longer updates any IP, and instead just restarts the add-on over and over again (see logs below)

I experienced something similar using v1.15.0 of the Duck DNS add-on.

With only IPv6 option set, I got the same log output as above.

With only IPv4 configuration set, it works as expected.

With neither set, it works as expected.
