Nginx change links to 127.0.0.1

Question

I have a flask app running in a docker container, and I configured nginx to redirect all requests to this container. Here's my nginx config:

server {
  listen 80;
  location / {
    proxy_pass http://127.0.0.1:5000;
    proxy_redirect off;
    proxy_http_version 1.1;
    proxy_set_header Connection "Keep-Alive";
    proxy_set_header Proxy-Connection "Keep-Alive";
    proxy_read_timeout 60s;
  }
}

On the frontpage I have a link to a subdirectory <a href="/sub/dir/">Test</a>, and when the page renders I can see it links to http://example.com/sub/dir. However when I click onto it browser shows http://127.0.0.1:5000/sub/dir and tries to reach my local.

Check what your browser is doing in the debugging tools when it ends up attempting to connect to the wrong address - does the browser get redirected by a 30x response, or is that the first request after clicking the good link? — Shane Madden, Apr 20 '17 at 15:09

My flask app have a redirect on that link to another page, after adding this to my nginx config it worked for me:

proxy_set_header Host $Host;
