I recently encountered an issue in a SharePoint 2013 deployment where viewing and editing of existing workflows would result in the standard error page “Something went Wrong”.
When I checked the ULS for the correlation ID I found a number of messages with a single Unexpected error
“System.IO.PipeException: The pipe endpoint ‘net.pipe://localhost/security TokenServiceApplication/appsts.svc’ could not be found on your local machine
I ran across a TechNet post that described the issue – Post
I checked on the WFE server and the two services were stopped.
- Net.Pipe Listener Adapter
- Net.TCP Listener AdapterHope this will save some of you time if you run into this issue in your environment
After starting the two services, then I was able to get to the workflow details as well as starting new workflows on ítems.
