@padkins64 

I have same Issue.

[#3]

Are you running a single, or multiple RDCB setup?

[#4]

I am running into this same issue, where you ever able to get it resolved and working? I am running a single instance on Server 2016. I am able to log into the webclient, but when I try to launch an application it fails with the same error above.

@Dennis_Peabody 

In my case, one of the RD Gateways required computer authentication. We disabled computer authentication, which made it less secure but did work.

We put the HTML5 client behind an Azure AD Proxy with preauthencation to keep it secure.

I have the same issue-- Can you tell me please if you were able to solve this issue?

@Dennis_Peabody 

May I know how I can check if the RD Gateway requires computer authentication? Is this via NPS?
