Sharepoint 2013. After successfully completed Register-SPWorkflowService command Workflow still is Not Connected at central administration.

After retry to register WF I`ve got following error:

PS C:\Users\Administrator> Register-SPWorkflowService -SPSite http:// my_site_name -WorkflowHostUri http:// windows_wf_azure_host_name :12291 -AllowOAuthHttp

Register-SPWorkflowService : The trusted provider certificate which is already in use.

Try with -Force. This will overwrite old params. Can be useful also in other cases when there is "something" registered but e.g. with errors.

  • I've rerun the cmdlet with -force, but CA still says Workflow is not connected, any other additional tips?
