Nginx – upstream sent too big header while reading response header – solution

If you get this kind of error in your nginx logs:

ERROR: *1754 upstream sent too big header while reading response header from upstream, client: X.X.X.X, server: XXXX

One solution that worked for me, was to set the fastcgi_buffers and fastcgi_buffers_size in nginx configuration file:

$ vim /etc/nginx/nginx.conf

Add the following params to your nginx configuration file:

    fastcgi_buffers 8 16k;
    fastcgi_buffer_size 32k;

Restart nginx:

$ /etc/init.d/nginx restart
