Cause

The error occurs because the businesslayer cannot validate the SolarWinds-Orion certificate in the server. The reason for this is due to the UDT plugin loading as its own process and as a 64bit process. For UDT, this is currently not supported and results in an error state. SolarWinds recommends to leave the default 32bit to ensure there are no issues.

Resolution

  1. Stop all Orion Services using the Orion Service Manager.
  2. Go to the install directory at Program Files (x86)\Solarwinds\Orion\UDT.
  3. Locate the file SolarWinds.UDT.BusinessLayer.dll.config and open in any text editor.
  4. Locate the line: 
    <SolarWinds.BusinessLayerHost LoadPlugins="true" SeparateProcess="true" Support64="true" />
  5. Change it to this: 
    <SolarWinds.BusinessLayerHost LoadPlugins="true" SeparateProcess="true" />
  6. Save the file.
  7. Restart all Orion Services using the Orion Service Manager.
