Почему NGINX не отдаёт сжатые файлы?

Проект NUXT SSR при сборке создаёт сжатые gzip и brotli файлы, но в Chrome DevTools показывается, что передаются не сжатые файлы.

// nuxt.config.js
...
modules: [
[
            "nuxt-compress",
            {
                gzip: {
                    cache: true
                },
                brotli: {
                    threshold: 10240
                }
            }
        ]
]

NGINX как прокси сервер скомпилирован с http_gzip_static_module и ngx_brotli
