In nginx.conf add the following.

client_max_body_size 10m; # single file to allow the maximum number of bytes requested by the client
maximum number of bytes the client proxy cache buffer # request> the request; client_body_buffer_size 128k

All configuration:

include /usr/share/nginx/modules/*.conf;
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
events {
worker_connections 1024;
}
