Issue: DDNS Authentication Failed with Cloudflare Integration
Hi,

I may be missing something, but I followed the instructions and ran them multiple times. However, I keep encountering the same error. I suspect the firewall might be blocking the connection, but I haven’t found anything in the logs to confirm this. Plus, the error message indicates "auth failed," which suggests a different issue.

Here’s what I’ve done so far:

-Verified the API Token
I tested the API token using the Cloudflare verification endpoint, and it returned the following:

{
    "result": {
        "id": "xxx",
        "status": "active"
    },
    "success": true,
    "errors": [],
    "messages": [
        {
            "code": 10000,
            "message": "This API Token is valid and active",
            "type": null
        }
    ]
}

So, the token appears to be valid and active.

-Error Log from the NAS

SYSTEM: System failed to register [xxx.xxx.xxx.xxx] to [hostname] in DDNS server [Cloudflare] because of [Authentication failed].

Additionally, I don’t see any access attempts or failures in the audit logs on Cloudflare.

-API Token Permissions

Zone Settings: Read
Zone: Read
DNS: Edit

The target A record exists, is proxied, and the IP address has been verified to be correct.

• NAS DDNS Configuration

Service Provider: Cloudflare
Hostname: nas.domain.com (even though it’s stated this field isn’t used)
Username/Email: nas.domain.com
Password/Key: API Key (copied and pasted to avoid typos)
External Address: Auto (Public IP)

I’m out of ideas about what could be causing this issue. Can anyone spot something I might have missed?

Thanks!

I tried turning off the proxy but still getting the same error
