Here are the steps SW support sent me:
- Please navigate to c:\Program Files (x86)\SolarWinds\Orion
- Locate the file SWTrapService.exe.config
- Locate
<add key="UseCollectorEndpoint" value="True"/>
- Change "True" to "False"
- Save the file.
- Load orion service manager found under start > solarwinds Orion > Advanced Features > Orion service manager.
- Locate the trap service. Stop it. Than restart it.
This worked and I've been receiving traps since.
