Environment:

How to reproduce:

docker run -p 80:80 kennethreitz/httpbin

Request http://localhost:80 in browser. Which leaves us with an error:

Internal Server Error

The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

And logs in the terminal:
