We have a parent list workflow (let's call it P1) that starts a child site workflow (C2) using the Nintex Call Web Service action. The Call Web Service action uses Workflow.asmx, Web method StartSiteWorkflow. We are using the web method to start the workflow in order to pass associationData.
P1 starts C2, as expected. However, after 1-2 minutes, P1 fails with error “Failed to invoke web service. Error returned from server: The operation has timed out”.
Despite the error message, C2 continues to execute and completes successfully.
This seems like it must be a configuration related specifically to Web Services, as we do not have this issue when starting the workflow using the Nintex Start Workflow action.
Has anyone seen this behavior before? Do you have any suggestions on what might be happening, or how to correct?
We have recently converted to SharePoint 2013. This was not an issue in SharePoint 2010.
Thank you for any input you might have!
