Technical Tip: FortiGate Cloud status is displayed as down in GUI after a failover

After a failover event in a FortiGate HA cluster, the FortiGate Cloud status remains in 'DOWN' state. However, log transmission to FortiCloud continues without interruption.

Before failover:

After a failover:

Use the following CLI command to verify the status:

diagnose fdsm central-mgmt-status

Logs are being transmitted to FortiGate Cloud consistently, with no interruptions observed as below:

diagnose test application forticldd 3
Debug zone info:
    FAZCLOUD:
    Domain:US
    Home log server: 209.40.117.74:514
    Alt log server: 209.40.117.77:514
    Active Server IP: 209.40.117.74
    Active Server status: up   <------------>
    Log quota: 500000000MB
    Log used: 28MB

If this is happening and the FortiGate is on a version below 7.4.10 or 7.6.5, try to restart a specific process with this command:

fnsysctl killall fgfmd

If that ends up working, then the culprit can be a known issue (bug ID 1212718). Upgrading to v7.4.10 or v7.6.5 would be the fix.

If that command does not work, or if the FortiGate is already on a fixed version, it can match a different bug that the developers are still investigating. The article will be updated when there is more information on that bug. 

Workaround: 
Re-registering the slave and refreshing the status restores the connection display.
