Fortigate 60F 60E dnsbot signature invalid update failed

[TomXu]

It started 24 hrs ago - I get this critical warning every 15 minutes...

It appears that all customers with 7.2.0 or 7.2.1 firmware are getting the warning. Devices model are FG60F, FG60E and FG80F.

Customers with 7.0.0 and 7.0.6 are fine.

Dear TomXu,

The error message sometimes appears if the device unable to update the "Botnet Domain Database" from Fortiguard server. Could you try to check if you have connectivity to Fortiguard server and if on dashboard any error you are getting "Unable to connect Fortiguard server" ?

Also please try to check if Botnet domain database update is installed or if any error you get for "Botnet Domain Database" by using command below:
diagnose autoupdate versions

If any error you get for "Botnet Domain Database", kindly check and try to update it manually and let us know if it works:
