Hi,  
When I “./launcher rebuild app” my Discourse and try to enter to my Discourse forum, its shows “502 Bad Gateway” error.  
I know it’s just 10 minutes but I think it’s more professional to show to our users a pretty error message when we update our Discourse.  
Thanks you,  
Miki  
P.S: sorry for my lame english. working on it!
