Tengo dos nombres de dominio conectados a dos servidores diferentes. un servidor back-end llamado www.funfun.io y un servidor front-end llamado 'v2.10studio.tech'

Quiero enviar una determinada ruta desde 'v2.10studio.tech' al servidor backend.

en el servidor backend hay otros nombres de dominio, lo que hace que sea necesario definir el host en el encabezado.

Configuración de nginx en el servidor backend.

 server { listen 443 ssl; server_name funfun.io www.funfun.io; ..... }

Configuración de nginx en el servidor frontend.

 server { listen 443 ssl; ssl_certificate /etc/letsencrypt/live/v2.10studio.tech/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/v2.10studio.tech/privkey.pem; server_name v2.10studio.tech; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_prefer_server_ciphers on; ssl_session_timeout 1d; ssl_stapling on; ssl_stapling_verify on; add_header Strict-Transport-Security max-age=15768000; add_header X-Frame-Options ""; location ~ /auth/(.*) { proxy_pass https://funfun/10studio/auth/$1?$query_string; proxy_set_header Host www.funfun.io; proxy_http_version 1.1; proxy_cache_bypass $http_upgrade; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-Port $server_port; }

los registros que obtengo al solicitar la ruta.
