ask Workflow stopped error no message

Dear all,

I try to workflow PR, and got the error workflow stopped error. there is no specific message error for the PR.

I check the event viewer, the error is

Object Server 01: An error has occurred in the services framework. Method: AifMessageInspector::AfterReceiveRequest. Error: System.ServiceModel.FaultException: Failed to logon to Microsoft Dynamics AX. at Microsoft.Dynamics.Ax.Services.AxServiceOperationContext.InitializeSession() at Microsoft.Dynamics.Ax.Services.AxServiceOperationContext.InitializeContext() at Microsoft.Dynamics.Ax.Services.AxServiceOperationContext.Attach(OperationContext owner) at System.ServiceModel.ExtensionCollection1.InsertItem(Int32 index, IExtension1 item) at System.Collections.Generic.SynchronizedCollection`1.Add(T item) at Microsoft.Dynamics.Ax.Services.AifMessageInspector.AfterReceiveRequest(Message& request, IClientChannel channel, InstanceContext instanceContext)

I already check the user there is no problem with the user in AD and System admin user.

Does any one can help me ?

Thanks
