You will need the sudo password.

sudo nano /etc/nginx/conf.d/uploads.conf

Replace contents with the following;

fastcgi_buffers 8 16k;
fastcgi_buffer_size 32k;

client_max_body_size 24M;
client_body_buffer_size 128k;

client_header_buffer_size 5120k;
large_client_header_buffers 16 5120k;

From  http   nginx org r large client header buffers  Syntax    large client header buffers number size   Default   large client header buffers 4 8k  Context   http  server Sets the maximum number and size of buffers used for reading large client request header  A request line cannot exceed the size of one buffer  or the 414  Request-URI Too Large  error is returned to the client  A request header field cannot exceed the size of one buffer as well  or the 400  Bad Request  error is returned to the client  Buffers are allocated only on demand  By default  the buffer size is equal to 8K bytes  If after the end of request processing a connection is transitioned into the keep-alive state  these buffers are released   so you need to change the size parameter at the end of that line to something bigger for your needs
