Why am I getting the "Content from the Website is being blocked" error on my Windows Server 2016?

By default the "IE Enhanced Security Configuration" setting is turned on on my Windows Server 2016. This will set all Websites in the Internet zone to the highest security validation level.

When you use Internet Explorer (IE) to access local Websites or Intranet Websites, security validation level will be much level, because they are trusted. And you will have no issues.

When you use Internet Explorer (IE) to access external Websites on the Internet, security validation level will be very high. And you will see the following error, because validations are failing.

Content from the Website listed below is being blocked 
by the Internet Explorer Enhanced Security Configuration. 
...

If you trust this website, you can lower the security settings 
for the site by adding it to the Trusted site zone.
