kav = Kaspersky Anti-Virus Software
I want to visit https://thenodecourse.com/ however you will see that in the developer tools the security certificate authority comes from an unknown source.
In the kav I try to add this site to the Trusted Zone as kav has blocked access to this website and when added to Trusted Zone its network activities (the websites) are no longer monitored - from the help docs.
However this does not seem to work and only works (succesful GET request) when kav is turned off. When turned off I get to see the Security Authority in the second screenshot which is from Let's Encrypt Authority X3.
On safari it does not block access when kav is on so I do not know why for Chrome when KAV is on.
