Nginx does not serve large files
For me the remedy were these two settings:
In the file:
/etc/nginx/nginx.conf
Add:
proxy_max_temp_file_size 0;
proxy_buffering off;
Between the lines client_max_body_size 128M; and server_names_hash_bucket_size 256;:
http {
client_max_body_size 128M;
proxy_max_temp_file_size 0;
proxy_buffering off;
server_names_hash_bucket_size 256;
The answer appears to be in these links. One, two. Basically, disable the disk cache
location / {
proxy_max_temp_file_size 0;
}
