Overview

A Server Error in '/' Application error shows up when accessing the SolarWinds Platform Web Console.



Upon reviewing the services using the SolarWinds Platform Service Manager, you'll notice that some of them have stopped; SolarWinds Collector, Recommendations, Module Engine, etc. However this can also be caused by a stopped Application Pool in IIS.



C:\ProgramData\SolarWinds\Logs\Recommendations\Recommendations.Services.log will show SQL-account logon errors below:
