Wyse vWorkspace 8.5 introduces a the ability to connect via a HTML5 capable browser without any configuration needed, neither on the endpoint nor the managed application. The translation from RDP to HTML5 is seamlessly processed on the Web Access Server.

If the logon to an application or desktop fails, and the browser just sits there showing the connection bar with a black background or a logon screen like shown in the Picture below, make sure RemoteFX is disabled on the RDSH Server or the hosted virtual Desktop.

This restriction is specifically called out in the Product Release notes of vWorkspace 8.5, and it might be overseen if an existing environment is upgraded where RemoteFX is already enabled to be used with native vWorkspace connectors.
