There was no endpoint listening

Issue: None of the documents (Pdf, word, Excel etc.) are opening in SharePoint intermittently. On opening the documents it is giving error “There was no endpoint listening” with correlation id.

Troubleshooting:

• Since the issue is happening intermittently it is possible that only one of the Web Front end server is affected
• Tried to open the site from each front end server and found that it is not working on of the Web Front end server
• Checked the ULS log with the correlation ID of the error and found below errors which are generated while opening the document:

Error:

System.ServiceModel.EndpointNotFoundException: There was no endpoint listening

 at net.pipe://localhost/SecurityTokenServiceApplication/appsts.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See

InnerException, if present, for more details. —> System.IO.PipeException: The pipe endpoint ‘net.pipe://localhost/SecurityTokenServiceApplication/appsts.svc’ could not be found on your local machine.      –

 — End of inner exception stack trace —    Server stack trace:    

 at System.ServiceModel.Channels.PipeConnectionInitiator.GetPipeName(Uri uri, IPipeTransportFactorySettings transportFactorySettings)   

Resolution:

Check Windows services and you will see “Net.Pipe Listener Adapter”  and “Net.TCP Listener Adapter” services stopped. Start the services and browse the site and you will see the documents are opening again without any issues.

Check the services on other front end servers as well.
