You see one or more of the following symptoms:
- The following error appears in the SharePoint server’s event log every hour:
“An error occurred while receiving the HTTP response to http://localhost:32843/SecurityTokenServiceApplication/securitytoken.svc. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.” - Users are unable to log in to SharePoint sites protected by claims authentication.
- Various SharePoint services such as user profiles, search etc. do not work as expected.
