Did you not see the part about how you made an error in your stratum. It is not your USERNAME that you put there. It can be confusing going off the front page, as Kano goes in the stratum, but is also used as the example for Usernames.
The red needs to be replaced by kano
stratum+tcp://stratum.USERNAME.is:3333
USERNAME.001
x
+--------------------+-------------------------------------+
+ Pool1: | stratum+tcp://stratum.kano.is:3333 |
+--------------------+-------------------------------------+
+ Worker: | Kano.worker |
+--------------------+-------------------------------------+
+ Password: | x +
+--------------------+-------------------------------------+
Of course replace 'Kano.worker' with your pool username.worker

If you have network issues using port 3333, you can also try any of:
stratum+tcp://stratum.kano.is:80
stratum+tcp://stratum.kano.is:81
stratum+tcp://stratum.kano.is:443
stratum+tcp://stratum.kano.is:8080The stratum server is in West-USA
There are other nodes located around the world that you may be closer to:
stratum+tcp://or.kano.is:3333 (Oregon)
stratum+tcp://nya.kano.is:3333 (NewYork)
stratum+tcp://nl.kano.is:3333 (Netherlands)
stratum+tcp://jp.kano.is:3333 (Japan)
stratum+tcp://sg.kano.is:3333 (Singapore)
