I've got 6 identical machines running IIS and Apache. Today one of them decided to just stop serving requests. I can access all of the webapps when I try from localhost/resource but when I try from url/resource I get a 404. I did a Get request against the machine that isn't working and I get this back:

• Server: Microsoft-HTTPAPI/2.0
• Connection: close

Compared to a working server:

• Server: Microsoft-IIS/8.5
• X-Powered-By: ASP.NET
• Content-Type: text/html

Tried searching for this problem but came up with nothing, anyone got any idea's?
