Hi, 

I have a development environment that I installed the Workflow Manager and yours dependencies. The SharePoint 2013 and database are in the same server.

I have two Webapps in my server. In First, the main webapp, I can't start the workflow. I created other webapp to test the workflow and in the second webapp the workflow works. But, I need to use the first webapp.

1. User profile synchronization is started.
2. The user that I am logged is available in User Profile list.

3. All workflow manager and service bus services are running .

4. The workflow works in other webapp

I saw in DebugTraces table of WFInstanceManagementDB4 database and there are some errors (webapp with problem):

I am using the HTTPDebuggerPro and there are some 401 errors:

Help me please!!!

Hi,

I understand that you failed to start workflow.

Please make sure you have created profiles for your service accounts, and make sure that the User Profile Service is associated with the "default" Application Proxy Group.

In addition, I recommend to use another account to start the workflow to check whether it caused by the account.

Hi Linda,

Though this is an old post, I'm currently facing the exact issue.

We have several web applications in the farm and I've tested the workflows in two web applications. One works and the other failed with 401 error, even when the workflow was started using the SharePoint Admin account.

RequestorId: c231852e-ebfe-e837-0000-000000000000. Details: RequestorId: c231852e-ebfe-e837-0000-000000000000. Details: An unhandled exception occurred during the execution of the workflow instance. Exception details: System.ApplicationException: HTTP 401 {"error":{"code":"-2147024891, System.UnauthorizedAccessException","message":{"lang":"en-US","value":"Access denied. You do not have permission to perform this action or access this resource."}}} {"Transfer-Encoding":["chunked"],"X-SharePointHealthScore":["0"],"SPRequestGuid":["c231852e-ebfe-e837-a7ca-2d48b43d07c3"],"request-id":["c231852e-ebfe-e837-a7ca-2d48b43d07c3"],"X-FRAME-OPTIONS":["SAMEORIGIN"],"Cache-Control":["max-age=0, private"],"Server":["Microsoft-IIS\/7.5"],"WWW-Authenticate":["Negotiate","NTLM"],"X-AspNet-Version":["4.0.30319"],"X-Powered-By":["ASP.NET"],"MicrosoftSharePointTeamServices":["15.0.0.4420"],"X-Content-Type-Options":["nosniff"],"X-MS-InvokeApp":["1; RequireReadOnly"],"Date":["Thu, 03 Sep 2015 03:51:51 GMT"]}   at Microsoft.Activities.Hosting.Runtime.Subroutine.SubroutineChild.Execute(CodeActivityContext context)   at System.Activities.CodeActivity.InternalExecute(ActivityInstance instance, ActivityExecutor executor, BookmarkManager bookmarkManager)   at System.Activities.Runtime.ActivityExecutor.ExecuteActivityWorkItem.ExecuteBody(ActivityExecutor executor, BookmarkManager bookmarkManager, Location resultLocation)

Both web applications uses the same application pool. User Profile Application Service Proxy is in the 'default' Application proxy Group.

What else can cause the 401 error?
