Traffic Manager Shows All Endpoints Status Degraded

I have two total endpoints that are both showing a status of "Degraded."

I read that this usually indicates that the monitor configuration is resulting in a response other than 200. However, testing with curl shows a 200 response for both endpoints. This is over http so there's no authentication.

It may be relevant that this is a Traffic Manager Profile (classic).

Here is an example of the curl result:

C:\Users\estarks>curl -I posguys-west.cloudapp.net:80/
HTTP/1.1 200 OK
Cache-Control: private
Content-Length: 76357
Content-Type: text/html; charset=utf-8
Set-Cookie: ASP.NET_SessionId=ztw4ebs0tnzelp4gkqfl1bi5; path=/; HttpOnly
X-Frame-Options: SameOrigin

I know that when all endpoints are degraded, they will essentially be treated the same as if they were online, but I'd like to resolve the degraded status.
