<PRE>  Can you get the clock example working? I'm not sure why the initial
upgrade request would fail; are you exporting init/4 in your handler? Are
your dependencies consistent (I.e., blow them away and regrab them in case
it's an older version of cowboy with a new version of bullet, or vice
versa, maybe)? Either way, starting from the example would allow you to
start from a set of working code and either avoid the issue entirely, or
isolate it from your code.
