Backend Nginx Configuration Issue with Port/Protocol Loss in Redirects #2493
Description
The frontend uses Nginx as a reverse proxy with HTTPS enabled, but it utilizes a non-standard web port (e.g., port 8443). After the frontend Nginx reverse proxy, the backend Nginx uses an HTTP connection on port 80. As a result, redirects from the backend lose the original port and protocol.
It is recommended to add absolute_redirect off; to the configuration file at .examples/docker-compose/with-nginx-proxy/postgres/fpm/web/nginx.conf.
This Nginx location configuration for reverse proxy：
location / {
proxy_pass http://127.0.0.1:80$request_uri;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Port $server_port;
proxy_set_header X-Forwarded-Scheme $scheme;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $host;
proxy_set_header Early-Data $ssl_early_data;
# Websocket
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $connection_upgrade;
}
