Workflow is hanging

Describe the problem/error/question

I have a workflow that was working normally, but now it is hanging every time it is called. Since it does not conclude, I have no execution data and cannot conclude where it is hanging. What shall I do to troubleshoot this problem?

What is the error message (if any)?

Hey @Martin_Neumann,

What is the workflow doing? Have you checked the application log or the event log to see if that shows anything? Are you are in queue mode it would be worth checking the worker logs as well.
