Have you modified default lines:

fastcgi_buffers 16 16k;
fastcgi_buffer_size 32k;

in /etc/sw-cp-server/config ?

 

[StefMG]

Yes, I have modify this value but in other file /etc/nginx/nginx.conf
how can restore default value?

I had try to restore this lines and restart nginx and sw-cp-service but sw-cp-service fail
