Unable To Load Fortiguard Ddns Servers List On Fortigate Firewalls Jun 2026

DDNS | FortiGate / FortiOS 8.0.0 - Fortinet Document Library

Note: The ddns-server option accepts FortiGuardDDNS , DynDNS , NoIP , etc., without needing the remote list. DDNS | FortiGate / FortiOS 8

If your FortiGate has multiple WAN links (SD-WAN) or uses a specific management interface, FortiGuard traffic might be exiting from an IP address that cannot route back properly. You can explicitly bind FortiGuard traffic to your primary WAN interface. Run these commands in the CLI: blocking the configuration of DDNS services.

When attempting to configure a new Dynamic DNS entry, the FortiGate cannot retrieve the list of available DDNS service providers (e.g., FortiGuard DDNS, No-IP, DynDNS). This results in an inability to select a server type, blocking the configuration of DDNS services. DDNS | FortiGate / FortiOS 8
