Nginx wp-admin Upstreamtime

Question

Eu configurei o Nginx conforme as instruções, tudo funciona, mas meu wp-admin está retornando um erro 504 ( upstream timeout ).

Tudo funciona corretamente, tudo reescreve, etc.

Eu tentei redimensioná-lo de volta ao básico sem cache etc., mas ainda nada.

fastcgi_cache_path /var/run/nginx-cache levels=1:2 keys_zone=MYAPP:100m inactive=60m;
fastcgi_cache_key "$scheme$request_method$host$request_uri";

    listen 82 default_server;
    listen [::]:82 default_server ipv6only=on;

    root /mnt/wpmount/nen;
    index index.php index.html index.htm;
