Users sometimes getting blocked to streaming sites even when they are in profile w/access
I have some users that are occasionally getting blocked to streaming media sites, even though they are in a security group that gives access. And it is sporadic, some days they can access. I noted a pattern in the firewall logs: they do not have their username in the "User" column. Those unaffected by this do have their username listed.
We are using FortiClient 5.6 on the computers, and FortiGate 300D (I don't know what version of software it is running).
