Nginx+php5-fpm - why are no errors shown?

Question

Nginx

In any case, be it a fatal error or just a warning - nginx returns 404
display_errors = on
The logs are empty.

Answer 1

see error.log of FPM itself

Answer 2

Perhaps the problem is in fastcgi_intercept_errors. And that nginx can't find the custom error page (500?). Look in src/nginx-bp/enable/errors.conf and make sure fastcgi_intercept_errors is set to "off".

Answer 3

besides the child is running and the service information is empty.

Answer 4

costs nginx-boilerplate as configs

Answer 5

Several times I have already encountered a similar problem, it was solved by increasing the size of the buffers

fastcgi_buffers 16 64k;
fastcgi_buffer_size 64k;
