Same here. After `./launcher rebuild app` the whole Discourse is down .. Error 521  
Already run multiple times `./launcher rebuild app` but did not helped, not like in the mentioned Thread above.

I was on **2.6.0-beta1**

Edit: after running it 3 more times, it came (after 10 min after finishing) back to life .. wtf?
