Currently, I've configured workflow manager in sharepoint server 2013 for using shareoint 2013 workflow in designer. But, while publishing the workflow, it shows following error:

System.InvalidOperationException: Operation failed with error Microsoft.Workflow.Client.WorkflowCommunicationException: The request was aborted: The request was canceled

enter image description here

I had registered the workflow service using:

Register-SPWorkflowService -SPSite 'http://sharepoint.example.com' -WorkflowHostUri http://workflowhost:23302 -AllowOAuthHttp -Force

So, what can be the solution? Is it out of memory problem?

The issue gets resolved after installing Cumulative Update for Service Bus 1.0 (KB2799752) and Cumulative Update for Workflow Manager 1.0 (KB2799754)


The last answer did not solve my issue. It triggered error when I ran the KB

Rebooting did solve the problem
