You should get smith like :
[NotebookApp] Kernel started: af66e841-321b-4201-81e3-4bb40bb1b6f4
[NotebookApp] Connecting to: tcp://127.0.0.1:57081
[NotebookApp] Connecting to: tcp://127.0.0.1:57082
[NotebookApp] Connecting to: tcp://127.0.0.1:57084

when clicking on a notebook. 

this make me think that ws connexion never occurred.
Do you have a proxy ?
If so you might want to configure your browser to explicitly avoid using proxy for localhost/127.0.01 , 
unplugging the ethernet cable is another way to test for it :-)

You can try  `%qtconsole` in the notebook to get a console attached to the same kernel… but I doubt the command ever get to the kernel.

keep us posted.
