Are you getting the error code: “The computer computer can’t verify the identity of the RD Gateway. It’s not safe to connect to servers that can’t be identified”? You most likely setup Remote Desktop Web Access (RDweb) with a self signed certificated.
The reason why you are getting this error is your machine doesn’t trust and can’t verify the identity of the RD Gateway.
