That the services are running within the windows service-overview or in taskmanager didn't mean that they are working properly from a qlikview point of view. But after a restart from the services it should be work. Before going deeper I would suggest to restart the whole server to be sure that there isn't any temporary issue. If the problem remained it will be rather difficult to find the reasons - maybe the QlikView Server Super Agent (and their log-files) from the PowerTools could be useful for this.
i did what you recommend and have the service have this error:
System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host
