What is the issue you’re encountering
I’ve had a policy for over a year that seems to have recently stopped recognizing the filter criterion of Application with YouTube. Now, when I browse to YouTube the exception I had created isn’t being recognized and the rule is not taking effect.
What steps have you taken to resolve the issue?
I have tried changing the filter criteria as a test to look for domain match for youtube.com and this does match properly. When I revert back to Application YouTube, the filter stops working again.
What are the steps to reproduce the issue?
This could be a bug in the traffic expression mechanism, but I doubt it. This particular traffic expression has two parts - the first is a content category selector with a boatload of categories selected and I specifically included Video streaming. That content category selector is paired with an AND to the next selector of Application where I’m doing a “not in” for a value of “YouTube” selected from the populated list. The effect of this is to exclude any video streaming services unless it is specifically the YouTube application. Again, if I change the second selector from application to regex does not match and put in youtube.com (appropriately regex’d) as a value - then Youtube will function properly again.
