I recently tried to configure arcanist on my machine. When I tried to connect it to my phabricator server, I got this error:
```
$ arc install-certificate
CONNECT Connecting to "http://myphabserver.com/api/"...
Usage Exception: Failed to connect to server (http://myphabserver.com/api/): [HTTP/404] Not Found

<h1>404 - Not Found</h1>

```
However, when I go to `http://myphabserver.com/` on my web browser, everything seems fine.
Did I missed something in my phabricator installation?
