proxy_set_header Host duplicates in the location

[Treverr]

I have a use case where I am proxying from my server to another hosted website. I found an issue where npm adds the proxy_set_header Host $host automatically, and I cannot override it manually, which I need to in this case because the $host is wrong and I needed to manually set it to the upstream host for CDN's to recognize it. $host is not defined so its null

I tried to do set $host in advanced but it just took my proxy offline.

For example, I need it to look like this:

  location / {
    proxy_set_header X-Forwarded-Scheme $scheme;
    proxy_set_header X-Forwarded-Proto  $scheme;
    proxy_set_header X-Forwarded-For    $remote_addr;
    proxy_set_header X-Real-IP      $remote_addr;
    proxy_pass       https://trever.mystrikingly.com:443;

    # Asset Caching
  include conf.d/include/assets.conf;

    # Force SSL
    include conf.d/include/force-ssl.conf;
    proxy_set_header Host "trever.mystrikingly.com";
  }

but NPM does not let that happen, it makes the configuration like this:

  location / {
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-Scheme $scheme;
    proxy_set_header X-Forwarded-Proto  $scheme;
    proxy_set_header X-Forwarded-For    $remote_addr;
    proxy_set_header X-Real-IP      $remote_addr;
    proxy_pass       https://trever.mystrikingly.com:443;

    # Asset Caching
  include conf.d/include/assets.conf;

    # Force SSL
    include conf.d/include/force-ssl.conf;
    proxy_set_header Host "trever.mystrikingly.com";
  }

Which does not work upstream.

Hi have your same problem !

I have some host that don't work if you don't set proxy_set_header Host

with the called fqdn hostname.

Have you found any solution ?

I had to manually go in and edit to remove that $host line that NPM adds only keeping my custom one.

Depending on your set up, You'll need to go into the docker itself 'docker exec -it nginsproxymanager sh' and and navigate to '/data/.../proxy_hosts' and edit the item manually.

@jc21 Is there no way to override this line, without resorting to this?

Hi, there, I had found a way to solve that. You can delete all your custom location in custom location tab, and add all location code in the advance tab. It works for me to add my 'proxy_set_header Host xxxxxxx', hope you too.

For posterity due to the complete lack of documentation of NPM:

1. In Details, use http, 0.0.0.0, 80 to show that settings on this page have no effect
2. In Advanced, set

   location / {
       proxy_pass "https://source.com";
       proxy_set_header Host "source.com";
   }
