UI fails to load with a "400 Bad Request" error

[Julie Pichon]

The TripleO UI is installed via packages by default on new undercloud installs. Although the httpd configuration files appear to be set up properly, trying to access the UI results in a "400 Bad Request - Your browser sent a request that this server could not understand" error.

The error looks to be from Apache, there is nothing looking particularly useful in the console logs or Apache logs.

Browser console: "Failed to load resource: the server responded with a status of 400 (Bad Request) - http://192.0.2.1:3000/"

tripleo-ui_access.log: 192.0.2.1 - - [28/Sep/2016:12:56:25 +0100] "GET / HTTP/1.1" 400 226 "-" "Mozilla/5.0"

The error logs are empty.

I know there are some transient issues at the moment while we're waiting for dependent packages to get picked up, but I believe this is failing before even loading any Javascript.

I installed the undercloud with export DIB_INSTALLTYPE_puppet_modules=source, in case that turns out to be relevant.

A few more observations:

* changing the loglevel to debug still doesn't produce anything useful in the logs
* accessing the tripleo-ui vhost is results in a 400 both from the undercloud itself, and from outside via port forwarding.
