View Agent Direct-Connection (VADC) Plug-In supports HTML Access to virtual machine-based desktops and RDS desktops. HTML Access to RDS applications is not supported. Install View Agent for HTML AccessTo support HTML Access, you must install View Agent on the virtual machine-based desktop with a special parameter. Set Up Static Content DeliveryIf the HTML Access client needs to be served by the desktop, you must perform some setup tasks on the desktop. This enables a user to point a browser directly at a desktop. Set Up Trusted CA-Signed SSL Server CertificateYou can set up trusted CA-Signed SSL server certificate to ensure that traffic between clients and desktops is not fraudulent.

You can prevent this error by disabling the HTTP/2 protocol on the desktop.
