Overview

When sending alerts in Network Performance Monitor (NPM), while using the GET/POST command, the error message appears:
Error 407 proxy authentication required

Environment

NPM 11 and earlier

Cause

The AlertManager.exe.config file does not have the <defaultproxy enabled="false"> </defaultproxy> tag.

Resolution

Edit the AlertsManager.exe.config file using a text editor:

  1. Open the C:\Program Files (x86)\SolarWinds\Orion\AlertsManager.exe.config file using Notepad or any text editor.
  2. Find the <system.net/>closing tag.
  3. Add the <defaultproxy enabled="false"/> into this section.
    The config should look like the following:
        <system.net/>

            <defaultproxy enabled="false"/>

            <settings/>

                   <httpwebrequest useunsafeheaderparsing="true"/>
  4. Restart the Alert Service.
