Connection not private page not reachable in chrome for testing browser

[kulabanta]

Hii
We started using Chrome for testing browser instead of normal chrome browser in our automated tests in selenium c# and
some of our testcases in which we are navigating to site with private connections or invalid certificates started failing because,
it is not showing the window to allow private connection and proceed further.
Instead it is showing site is not reachable .
we are using this '--ignore-certificate-errors' argument in chromeOptions of ChromeDriver to skip the connection not private page. It is able to skip the page in normal browser but not in chrome for testing browser.
attaching the screenshot for reference
In the screenshot left side is normal chrome browser and right side is chrome for testing browser.

In principle there should be no differences between CfT and Chrome regarding certificates.

Is there some public URL wherein this reproduces?
