Gateway timeout 504 when moving from django development server to Nginx/uWSGI? -


i have django app talks remote raspberry pi acquire imagery through pi's camera. whenever test "get new image" button in app, browser gets hung 60 seconds , image never arrives.

the raspberry pi trying post image django app supposed save persistent storage.

the logs of nginx show 504 "gateway timeout" @ 60 second mark. however, worked smoothly when using django development server , took second post image. what's going wrong now?

make sure you're running uwsgi multiple processes , threads.

you can test on uwsgi command line adding:

--processes 4 --threads 2

or in uwsgi ini file:

processes = 4 threads = 2

if pi posting image app while waiting display result user, uwsgi needs able handle both things concurrently.

another possibility django app uses threads itself, , without --threads n or --enable-threads option uwsgi, gil isn't enabled when app runs. adding --enable-threads (or enable-threads = true ini file) enable gil without starting multiple app threads.

see a note on python threads in uwsgi docs if suspect app's threading may problem.

in case, make sure you've provided enough concurrency if you're seeing gateway timeouts.
