I was trying to upload a data file of around 600 MB in my project which is hosted in digital ocean. It tries to upload but 502 Bad Gateway Nginx error is shown.
While the upload completely works fine on my local system.
When I tried:
sudo tail -30 /var/log/nginx/error.log
It shows:
[error] 132235#132235: *239 upstream prematurely closed connection while reading response header from upstream, client: client's ip, server: ip, request: "POST /submit/ HTTP/1.1", upstream: "http://unix:/run/gunicorn.sock:/submit/", host: "ip", referrer: "http://ip"
After,
sudo nano /etc/nginx/sites-available/myproject
the nginx code
server {
listen 80;
server_name ip;
client_max_body_size 999M;
location = /favicon.ico { access_log off; log_not_found off; }
location /static/ {
alias /root/static/;
}
location / {
include proxy_params;
proxy_pass http://unix:/run/gunicorn.sock;
}
}

Gunicorn is working. My memory logs are:
Only with large file uploads, I have 502 gateway errors
Hi there @rikeshk012330,
It looks like that your Gunicorn service has crashed and Nginx is unable to connect to it.
To fix the error you have to start the Gunicorn service.
