nginx on separate host as reverse proxy with domain name

[NullBy7e]

Hello,

I am trying to configure my nginx instance in such a way that it will reverse proxy proxmox.internal to 10.0.1.1:8006.

All of the guides I find, including the official documentation explain how to do this but they do not include configuration for a domain name, and my nginx instance is located on a different host.

Could someone help me get this to work? I would appreciate it!

Config:

server {
    listen 80;
    server_name proxmox.internal www.proxmox.internal;
    rewrite ^(.*) https://$host$1 permanent;
}

upstream proxmox {
    server 10.0.1.1:8006;
}

server {
    listen 443 ssl;
    server_name proxmox.internal www.proxmox.internal;
    ssl_certificate /cert/pve-ssl.pem;
    ssl_certificate_key /cert/pve-ssl.key;
    proxy_redirect off;

    location / {
        proxy_ssl_protocols TLSv1.2;

        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";

        proxy_buffering off;
        client_max_body_size 0;
        proxy_connect_timeout 3600s;
        proxy_read_timeout 3600s;
        proxy_send_timeout 3600s;
        send_timeout 3600s;

        proxy_pass https://proxmox;
    }
}

When I navigate to https://proxmox.internal I get into an infinite loading loop.
