If you ever got the “500 Internal Server Error” page served by your NGINX web server, it may be puzzling what is really wrong from the page itself:

O que verificamos

?

Such issues can trigger a 500 error like the image above, particularly when fastcgi_intercept_errors setting is on in NGINX. This configuration makes NGINX treat upstream errors as its own, thus instead of seeing errors generated by PHP, you see the error generated by NGINX itself.

Precisa de mais evidência Confiança 54%

As evidências fornecidas mencionam erros upstream do FastCGI e como isso gera mensagens de erro no NGINX (por exemplo, problemas de buffers e timeouts que causam 502/504) e discutem consolidação de logs entre PHP-FPM e NGINX, mas não há confirmação direta de que a opção fastcgi_intercept_errors por si só provoca especificamente um erro 500 e substitui a mensagem de erro gerada pelo PHP. Fontes: fórum FreeBSD sobre logs PHP-FPM/NGINX (https://forums.freebsd.org/threads/please-help-to-send-php-fpm-error-logs-to-nginx-error-logs.90277/), artigo TechOverflow sobre 'upstream sent too big header' (https://techoverflow.net/2020/01/28/how-to-fix-nginx-fastcgi-error-upstream-sent-too-big-header-while-reading-response-header-from-upstream/), e o gist sobre erros comuns FastCGI/PHP-FPM (https://gist.github.com/CMCDragonkai/830c55305de28b7c5d94). Precisaríamos de documentação oficial do NGINX ou de um exemplo reproduzível que mencione explicitamente fastcgi_intercept_errors e o comportamento de transformar erros do upstream em um 500 para avaliar plenamente a afirmação.

Internal server problems in NGINX Apart from PHP-FPM

Misto Confiança 42%

As fontes indicam claramente que um erro 500 no NGINX pode resultar de problemas internos ao próprio NGINX (configuração, permissões, recursos) e não apenas de PHP-FPM ou outros backends. Por exemplo, DailyExamine afirma que 500 pode ocorrer por configurações, permissões ou problemas de recurso (https://dailyexamine.com/nginx-500-internal-server/), o guia em Ruby-Doc discute que 500 é um código genérico do servidor que muitas vezes deriva de scripts backend, configurações ou permissões (https://ruby-doc.org/blog/500-internal-server-error-nginx-causes-solutions-prevention/), e o artigo no Appuals também descreve múltiplas causas de 500 que não são necessariamente PHP-FPM (https://appuals.com/nginx-shows-500-internal-server-error/). Essas fontes suportam a afirmação de que há problemas internos ao NGINX além do PHP-FPM que podem causar erros 500.
