Assistance Needed with Nginx Reverse Proxy Configuration

We have configured a reverse proxy on our Nginx server, intending to serve our blog hosted at blog.djaayz.com through the URL djaayz.com/blog. Below is the relevant section of our Nginx configuration:

location = /blog {
    rewrite ^ /blog/ permanent;
    rewrite ^/blog(/.*)$ $1 break;
}


location ^~ /blog/ {
    proxy_pass http://blog.djaayz.com;
    proxy_set_header Host $host;
    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;
}

it redirects and loads as:

In the Webflow dashboard, the only setting we’ve adjusted is setting the base URL to https://djaayz.com/ in the advanced settings.

Could you please advise what might be going wrong with our configuration? Are there additional settings needed in Webflow, or any changes required on our Nginx server to ensure the proxy pass works as intended?
