i have same problem, the notification server is working and it logs notifications like on new message in Conpherence app, but nothing get's updated in notifications ui and it also just says "Setting Up Client".

ok figured it out the problem for me was because of this bug T9293

@nnnn20430: Thank you for the reference. Did you apply the patch, included in T9293: WebSockets access problems with reverse SSL proxy ?

@ablekh i just added a "fastcgi_param HTTPS on;" in nginx config for phabricator

@nnnn20430: I see, thank you for clarification. I will give that a try.

@ablekh : Were you able to solve this issue in the end? We're experiencing the same problem and are not using any proxy server.

@chr86: Yes, I was able to solve this a while ago. If I remember correctly, I have just used the following instructions and, perhaps, restarted the server once or twice: https://secure.phabricator.com/book/phabricator/article/notifications. Hope this helps. I think I wrote down the solution steps, but couldn't find that document at the moment (maybe I didn't write anything down) - please let me know, if you are successful in that.
