The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /focus/chat/2646169/posts.
Reason: Error reading from remote server
Weird error. It means that the server and the proxy aren't understanding each other. It can be a misconfiguration of either or some odder thing. In short, I have kind of nothing, strange thing :(
So I think we should place the blame at Obama’s feet.
