See who is being denied from Views

I've seen this a bunch of times. In the Views tile it shows Denied greater than 0 and is red. If I go into Views>Diagnostics I get a little more info. But I still don't know who is getting denied, why, or when. Is there a way to see this detail?

https://helpcenter.canarylabs.com/t/h7yfymr/using-views-diagnostics-version-25 says that it's for people trying to get a license when none are available. But the systems have unlimited user licenses, so what is this Denied from?
