"Can not receive data from Automation Workshop Service"


The error indicates that Automation Workshop Manager can not retrieve data from Automation Workshop Service which is the core component of the software. As a consequence Tasks are not manageable and user can not access information on actual processes.


Possible cause for inability of Automation Workshop Manager to receive data from Automation Workshop Service is either overload of computer due to executing lots of Tasks simultaneously or unexpected communication error.

The most common cause is when the Service is under very heavy load and the Automation Workshop user interface can't display thousands of event messages per second. This is also a case when you are connected to a remote machine over a very slow internet connection, and the network can't handle such a load.

Note, that no information is lost—everything is still logged into the Service.log file. If the issue persists for a remote Automation Workshop instance, you can adjust the Event reporting option to display less events, and then use the Log Manager for complete event log. For a local machine, you can adjust the Display in Log Pane Task setting.
