IIS 7.5 returning a 404 for one MVC route, but only when deployed

I have a site that is working fine on my local dev machine. When I run everything in IIS Express, the site is working fine. However, when i deploy my app to production, everything but one route is working. That one MVC route is returning a 404 error.

I turned on Failed Request Tracing and have the trace file. All i can see in it is that there is a warning on the “Module Set Response Error Status” and it says it came from the ManagedPipelineHandler.

There’s nothing I can find unique about this route. Everything I can find says it should work, but for some reason it doesn’t.

The Failed Request Tracing reads like a set of stereo instructions. I’m not sure what I should be looking for.
