SignalR Scaleout with Redis - redis

Question

http://www.asp.net/signalr/overview/signalr-20/performance-and-scaling/scaleout-with-redis
I followed this link to scaleout my simple signalr chat visual studio project.
I made my ubuntu virtual mchine on azure which runs redis.
I added GlobalHost.DependencyResolver.UseRedis("server", port, "password", "AppName"); to my startup class and right now I am only testing it on my machine , not other servers.
But it does not work.
As soon as I put in that line my chat program gets stuck at line 1(see below) and never reaches line 2.
1)$.connection.hub.start().done(function () {
2) $('#sendmessage').click(function () {
What am I doing wrong?

It's best to setup server and client-side logging. This page details it http://www.asp.net/signalr/overview/signalr-20/performance-and-scaling/scaleout-in-signalr.

So after 2 months someone asked for more detail... so here's it copied and pasted

You need to enable pub/sub channel on redis server.
Steps:
Open redis.windows.conf file
Go to the Event notification section
Add or uncomment notify-keyspace-events E
Restart redis server.
