False positives on proxy detection

[Paulo]

Good day all,

We are running 16.5.2 and we have had UT in place since 2010. It is the foundation of the network and I couldn't operate this network without it. At least in the way we run now. I love it.
Curious issue has popped up. Somehow there are many users being detected as proxy use when there isn't one. I know this because one was my own. I do not allow proxies and accidently shut down about 30 innocent users.
Normally this runs for weeks and months without a problem but I rebooted just now in case. We will see.
Anybody know what's going on?

Detected by what? Where are you seeing this?

Both Web Filter and Application Control rely on third-party definitions (for Categories and application signatures, respectively) so it's possible that the provider has incorrectly defined some traffic. In the case of Web Filter, it's more easily resolved using the 'suggest a different category' option on the Site Lookup tab and a temporary Pass Site rule. In Application Control, updates to definitions take a lot longer and you may need to get creative with Application Control Rules.

Post a screen capture of the Webfilter blocked sessions.

There is no blocking going on. I see the tag from the sessions list.
