I used this guide to set it up and it was working to server my django app for a while, but after adding a new django module, without touching any of the nginx or uwsgi configs, now the server leads to 502 502 Bad Gateway error. The nginx error.log says:<\/p>\n

\n

*1 upstream prematurely closed connection while reading response header from upstream, client: x.x.x.x, server: blabla.com, request: “GET \/ HTTP\/1.1”, upstream: “uwsgi:\/\/127.0.0.1:4000”, host: “x.x.x.x”<\/p>\n<\/blockquote>\n

I appreciate your hints to resolve this.<\/p>\n

    This error usually indicates that your Django application has crashed (raised an unhandled exception). You should be able to get more information from the uwsgi logs at \/var\/log\/uwsgi<\/code>.<\/p>\n<\/li>\n<\/ol>\n
