We had an issue where Workflow Manager proxy was not working, generating the following error:

"SharePoint 2013 workflow requires a compatible workflow service configured with SharePoint such as Workflow Manager. The workflow service is either not installed or not configured."

Like this:

We did a certificate update and all of sudden this happened.

Tried to run the Register-SPworkflowService one time to register the proxy but it ends up with the following error:

“Register-SPWorkflowService : Failed to register because the farm or partition is already registered with a workflow service

At line:1 char:1
+ Register-SPWorkflowService -SPSite
https://ke-sit.krossfarm.com/sites/Workfl ...
+ CategoryInfo : InvalidData: (Microsoft.Share...WorkflowService:
RegisterSPWorkflowService) [Register-SPWorkflowService], ConfigurationExce  ption   + FullyQualifiedErrorId : Microsoft.SharePoint.WorkflowServices.PowerShell
   .RegisterSPWorkflowService ”

Ran the command with –Force parameter. This time it successfully completed but still generated the same error in the Central Admin.


Clearly, we have to unregister and register the Workflow Proxy.

  • Unregister Workflow Proxy:
    • Go to Central Admin > Application Management > Manage Service Application > Click on the Workflow Service Application Proxy
    • Select it and from the Ribbon click Delete
  • Register the Workflow Proxy
    • Now run Register-SPWorkflowService in the PowerShell window. Would recommend using the –Force parameter.
