Troubleshooting FDN connectivity
If your FortiGate unit is unable to connect to the FDN, check your configuration.

configure your network to allow the FortiGate unit to use HTTPS on port 443 to
connect to the Internet.
You might have to connect to an override FortiGuard server to receive updates.
See “To add an override server” on page 167. If this is not successful, check your
configuration to make sure you can connect to the override FortiGuard server from
the FortiGate unit.
Push updates might be unavailable if:
• you have not registered the FortiGate unit (To register your FortiGate unit, go
to Product Registration and follow the instructions.)
• there is a NAT device installed between the FortiGate unit and the FDN (see
“Enabling push updates through a NAT device” on page 169)
• your FortiGate unit connects to the Internet using a proxy server (see “To
enable scheduled updates through a proxy server” on page 168).
