Hi I am using an NGINX server and can’t login to the panel…
The console says
POST https://DOMAIN.COM/api/auth/login 403 app.js:1

permissions of accounts and sessions folder are set. I even tried 777

my nginx conf

# FORGE CONFIG (DO NOT REMOVE!)
include forge-conf/MY_DOMAIN/before/*; # MY_DOMAIN is obviously my real domain

server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    server_name MY_DOMAIN;
    server_tokens off;
    root /home/forge/MY_DOMAIN/public;

    # FORGE SSL (DO NOT REMOVE!)
    ssl_certificate /etc/nginx/ssl/MY_DOMAIN/814701/server.crt;
    ssl_certificate_key /etc/nginx/ssl/MY_DOMAIN/814701/server.key;

    ssl_protocols TLSv1.2;
    ssl_ciphers ECDHE-RSA-AES256-GCM-SHA512:DHE-RSA-AES256-GCM-SHA512:ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-SHA384;
    ssl_prefer_server_ciphers on;
    ssl_dhparam /etc/nginx/dhparams.pem;

    add_header X-Frame-Options "SAMEORIGIN";
    add_header X-XSS-Protection "1; mode=block";
    add_header X-Content-Type-Options "nosniff";

    index index.html index.htm index.php;

    charset utf-8;

    # FORGE CONFIG (DO NOT REMOVE!)
    include forge-conf/MY_DOMAIN/server/*;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location = /favicon.ico { access_log off; log_not_found off; }
    location = /robots.txt  { access_log off; log_not_found off; }

    access_log off;
    error_log  /var/log/nginx/MY_DOMAIN-error.log error;

    error_page 404 /index.php;

    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;
    }

    location ~ /\.(?!well-known).* {
        deny all;
    }
}

# FORGE CONFIG (DO NOT REMOVE!)
include forge-conf/MY_DOMAIN/after/*;

anybody has any lead on why this is happening?

The problem are probably the security header. Try removing them, and if it works then, re-add them with exceptions for the Panel.
