    Having the same problem. Started using fortiguard servers and now keep getting Dns lookup errors and server failed to respond errors. Could there be some kinda mis configuration.

    Put on 5.4.1, tried this feature, had the same problems.
    Turned the feature back off - no problems.

    Can replicate this issue too on customer equipment, unsure on root cause as I have 5.4.1 at home and have no issues.
     
    Have logged FortiTAC case # 1800082 -- will update here with resolution if I remember.

    Hi,
     
    I got help from the fortinet support. They changed settings (can't remember details). But the changes are not solved the problem completely. The feature sems to me no stable enough.
     
    Sorry to have no better news for you :-(
     
    Best regards

    I had problems with the DNS Server too, it's the one starting with 212.x.x.x I think. I removed it from the DNS configuration and replaced it with the google DNS, now everything seems to be working.

    Sure, using Google's servers should easily fix the issue. But, isn't the point of this feature that Fortiguard maintains a DNS database and servers, that filter out known malicious endpoints and other stuff that should be avoided? Seems to me that the issue is with Fortiguard's service here, perhaps their DNS infrastructure cannot handle the load generated by all of the Fortiguard devices out there...

    if you need other parts of the configuration mike let me know!
     
    config system fortiguard
    set service-account-id "x.x.x.x"
    set sdns-server-ip "208.91.112.220"
    end
     
    config system dns
    set primary 208.91.112.53
    set secondary 208.91.112.52
    end
     
    config system dhcp server
    edit 1
    set forticlient-on-net-status disable
    set default-gateway 192.168.255.2
    set netmask 255.255.255.0
    set interface "internal"
    config ip-range
    edit 1
    set start-ip 192.168.255.110
    set end-ip 192.168.255.210
    next
    end
    set timezone-option default
    config reserved-address
    x.x.x.x
    end
    set dns-server1 8.8.8.8
    set dns-server2 8.8.4.4
    next
