I met a trouble with the size of my request. I have tried to send 14 pictures in my request so the body_size was superior to 1.5 Mb, I got “413 Entity too large”. So I followed instructions I found here and increased the client_max_body_size to 10 Mb in nginx.conf https://datanextsolutions.com/blog/how-to-fix-nginx-413-request-entity-too-large-error/
Now the problem is not fixed, I dont meet 413 anymore but now I meet “502 Bad Gateway” and a part of my request is readed (10 / 14 pictures are correctly uploaded and I made a lot of test, the problem doesn’t come from the image)
When I run “sudo tail -F /var/log/nginx/error.log” I can see “upstream prematurely closed connection while reading response header from upstream”
It is really strange because when I run the application in virtual environment on server The request is correctly launched and the 14 images are uplaoded.
Notice that I already investigate the timeout response and added this in nginx/sites-enabled
include proxy_params; proxy_pass http://unix:/run/gunicorn.sock; proxy_read_timeout 300s; proxy_connect_timeout 75s;
Thanks for reading
