UnrealGameSync Metadata Server Issue

Apologies for ressurecting this once again.
I have gone through this step list (good job setting it up) but I still am having issues.
It runs from visual studio, but not from the IIS directly (still on the 404 when doing host/api/latest)

So am trying to find how you guys debugged this (I did set the Failed Request Tracing, but that doesn’t seem to help much)

Question, where are you setting ApiUrl?
I am setting it directly on DeploymentSettings.cs

Side note, I can’t make the Direct Web Publish work, I am using Web Deploy Package instead.
