Sites blocked when using default internal -> wan policy

[generaltab]

Hello

I’m setting up a new FortiGate 90D. When the default internal -> wan policy is enabled, desktops on my LAN are blocked from pretty much every site I've tried (attached). I’ve resorted to using a alternate policy with no AV, web, app, SSL filtering. Any ideas what might be going on?

Thanks

Review any of the recent threads about corrupted AV engine, including this one.

Also, check if there was any AV engine update happened recently on the Fortigate.

you can verify it on the GUI (System > Config > Maintenance > Fortiguard ) or with the command 'diag autoupdate versions'
