Overview

This article addresses the following error that appears while upgrading the additional polling engine after migrating and upgrading the Orion main server application to a new server:

Cannot Connect to the Main Orion Server

The server is unable to establish a connection to SolarWinds Information Service on the main Orion server.

Environment

NPM 11.0 and later

Cause 

This occurs because the additional polling engines are still connected to the old database and are still trying to connect to the old primary server.

 

Resolution

  1. Uninstall everything from the additional polling engine. Refer to Uninstall, change or repair a program
    Note: Do not run the Configuration Wizard while uninstalling a SolarWinds application.
  2. Rerun the APE NPM installer.
  3. When prompted for the Hostname or IP address of the main Orion server, enter the new server details.  
  4. When prompted for the Database settings, enter the new SQL server details.
  5. Complete the wizard.
