The Orion service is regularly reset

The Orion service is reset regularly once every 24 hours.


  • Any Orion module when you have installed UDT version earlier than 3.2.4



The issue is caused by the computer having blocked internet access with a proxy that returns a 404 status error. The issue was resolved in UDT 3.2.4.


Detecting the issue

To detect the issue, check the business layer log (located in %programdata%\Orion\Logs) for the affected application, and look for the following exception:

System.Net.WebException: The remote server returned an error: (404) Not Found.
at System.Net.WebClient.DwonloadDataInternal(Uri address, WebRequest& request)
at System.Net.WebClient.DownloadData(Uri address)
at System.Net.WebClient.DownloadData(String address)
at SolarWinds.Licensing.Framework.Store.CertificateHandling.RetrieveCertificateFromWeb(HttpProxyDetails proxyDetails)

During communication with the licensing server, the error code 404 is sent to the licensing framework by the proxy server. If the computer were behind a firewall, a connection would not be created. However, in this case, the error 404 is not handled and an exception is thrown.


As a workaround, prevent the licensing framework from communication:

  1. Open regedit on the affected computer.
  2. Locate the key: HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{15119A76-31E3-4C58-AD65-5BCCF704B5C5}
    Or on 32-bit systems: HKEY_CLASSES_ROOT\CLSID\{15119A76-31E3-4C58-AD65-5BCCF704B5C5}
  3. Make the following change for each subkey except for InprocServer32 and TypeLib:
    1. Open the key.
    2. Update the value of Loc to a significantly higher value. For example, if the value is 8d2e8e3753fc68e, update it to ad2e8e3753fc68e.

The above settings will prevent the licensing framework from communicating with the licensing server.
