This article describes the issue when you are unable to get to the SolarWinds website with a SOAP error and you receive the following prompt from the Businesslayerhost:

2016-01-11 17:03:33,666 [7] WARN  SolarWinds.Orion.Core.Common.ServiceHelper - Waiting for SWIS v3.0 start. Attempt 40, exception message: "There was no endpoint listening at net.tcp://nan-no-vpor01:17777/SolarWinds/InformationService/v3/Orion/certificate that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details."

Looking at information service v3 log it has the following,

2016-01-11 16:38:25,452 [6] ERROR SolarWinds.InformationService.Core.InformationServiceService - (null)     Information Service failed to open a channel.

The Key part of the error is that it references DPA, "SolarWinds.Data.Providers.DPA.V3.Federation.FederationServiceProxy.ExecuteActionWithImpersonation"


NPM version11.5 with DPA integration


This is a known issue that's currently being investigated by our Dev team. 


  1. Remove the DPA integration.
  2. Stop all Orion services.
  3. If you are unable to access the website, run the queries below: 

DELETE FROM [WebSettings] WHERE SettingName IN ('DPA.DpaServiceUserAccountId', 'DPA.ServerUrl', 'DPA.OrionHostname')
DELETE FROM FED_Subscription WHERE ServerId IN (SELECT ServerId FROM FED_RemoteInformationServices WHERE Tag = 'DPAO')
DELETE FROM FED_RemoteInformationServices WHERE Tag = 'DPAO'

  1. Run the Above Query on the Orion DB.
  2. Start all Orion services.
