The message below indicates an orderly disconnect on the web application side. Given how brief that connection is, it looks like the underlying RDP connection has failed early in the connection process. You would need to check the guacd logs to see what might be going wrong there, but the cause is most likely incorrect connection parameters within your JSON.
