Why does the Chrome address bar show a "Not Secure" warning in the video log?

When you view the video log, you may see the following warning in the Chrome address bar:

This warning appears because of the way Basic Authentication and custom hosts are set up.
Even if this warning appears in the address bar, requests/responses will be securely encrypted as long as the SSL certificate is set up correctly.

If a Workspace has at least one Basic Authentication or Custom Host set up, the above applies to all test execution within the same Workspace, regardless of the test target website.

In this case, the warning will appear in tests for websites that don't have a Basic Authentication or a custom host set up.
