almost all web-pages blocked

[Mogli]

good day

since about an hour the fortigate blocks almost all internet sites. is it possible that an update in the dns filter is broken? we have 4 Fortigate 61E in different location in use. If I disable the DNS filter in the ipv4policy (LAN-WAN) everything works fine again.

Hi 

Can you share the error ? Does FG to fortiguard was stable ?

Hi Mogli,

Please help us with the output of 

config sys dns
sh full

Also, please confirm if all the 4 Fortigates had the same issue at the same time? Could you confirm if they are connected to each other?

Regards,

Vimala

Hi Mogli,

As per the detail shared by you after disabling the DNS filter, it started working in this case you need to check the Fortiguard connectivity status at the time of issue

exec ping service.fortiguard.net

exec ping update.fortiguard.net

exec ping guard.fortinet.net
