Error debugging web app IISExpress in VS 2019 "The connection for this site is not secure"

Question

I'm getting an intermittent (but most of the time) error when trying to debug a web app with local IIS (Edge), and can't find any info on what might be happening.

I'm a local admin, running VS 2019 as Admin on Win 10, and have verified that my Virtual Directory settings are correct. This is a shared project running OK for others, so I know it has to be something local.

Here's the error:

Any help or ideas would be appreciated.

Maybe your internet is not set to the right settings.
That happened to me as well. But had to change my network settings.
