I am trying to install the Windows 2016 RDWeb HTML5 client on a Windows 2016 RDGW server using these instructions from Microsoft CLICK HERE

I was able to successfully do this on one of our regional server farms last week.

This week, performing the exact same steps, I am getting this error in the screenshot.

enter image description here

I then tested the command on my original server build and it is now generating this error as well.

Has anyone encountered this error as I am unable to find the cause? Also, I know it says to check my internet connection however, my RDWeb portal works but requires the HTML5 version or better in order to support Chromebooks.


You may be using TLS 1.0. Try this first:

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
