title: .NET Core Web api call ERR_CONNECTION_RESET only on IIS - other calls working
body: <p>I'm now at a complete loss...</p>
  
  <p>I have a .NET Core web app, and running locally everything is working. There's a number of WebAPI end points, again all working as intended with <code>GET</code> and returning JSON correctly.</p>
  
  <p>When I publish to IIS, one, and only one of these end points stop working and throw <code>(failed) net:ERR_CONNECTION_RESET</code> (in Chrome - other browsers throw their own errors).</p>
  
  <p>What is peculiar is that all the other Web API calls are working, all in the same environment and calling the same database, using the same context and EF data service.</p>
  
  <p>What I can't figure out, is how to get detailed logs from Kestrel into some other logging services, either Windows Event Viewer, a text file, emails or anything else! I've not used much of the logging middleware, with the intention to hook that up as we get closer to production.</p>
  
  <p>What's the best way to try and troubleshoot this in IIS 8 on Windows 2012 R2 with the .NET core Kestrel web server?</p>
