Cloudflare Free Plan DDNS Issue

[smccloud]

I am using the Cloudflare free plan, and need a new DDNS client due to my ISP (Spectrum) screwing something up with gateway pinging, causing the one built into pfSense to no longer work. I like the UI on this one, telling me if everything is up to date. I got DuckDNS working without issue, but I cannot get Cloudflare to work. Here is my sanitized config file.

{
    "settings": [
        {
			"provider": "duckdns",
			"domain": "subdomain.duckdns.org",
			"token": "tokenhere",
			"ip_version": "ipv4",
			"ipv6_suffix": ""
		},
		{
			"provider": "cloudflare",
			"zone_identifier": "smccloud.com",
			"domain": "subdomain.smccloud.com",
			"ttl": 600,
			"token": "tokenhere",
			"ip_version": "ipv4",
			"ipv6_suffix": ""
		}
    ]
}

The error I get is as follows.

ERROR getting record id: HTTP status is not valid: 404: {"result":null,"success":false,"errors":[{"code":7003,"message":"Could not route to /client/v4/zones/smccloud.com/dns_records, perhaps your object identifier is invalid?"}],"messages":[]}

I'm sure its something simple I'm doing wrong, but all I see for a Zone ID in my dashboard is smccloud.com, nothing else.

late to the party but your zone identifier is most likely wrong. It should be a long string, 32 chars in my case. And your domain should probably be the root domain without any subdomain.
Assuming you point your subdomains at "@", as in the root IP in cloudflare.
Also check if you've proxied your (sub)domain, would then also need the "proxied": true section in your config

I also recommend to use all the protection cloudflare offers in the free plan. Their security rules editor is pretty user friendly
