Location directive ( location /{ ) causing proxy host to land at openresty landing page

[cirnoscodingclass]

Checklist

• Have you pulled and found the error with jc21/nginx-proxy-manager:latest docker image?
  • Yes
• Are you sure you're not using someone else's docker image?
  • Yes
• Have you searched for similar issues (both open and closed)?
  • Yes

Describe the bug
When working under the Advanced tab of Edit Proxy Host I place the following addition to the config dialogue box

location / {
   proxy_set_header Host $http_host;
   proxy_set_header X-Forwarded-Host $http_host;
   proxy_set_header X-Forwarded-Port $server_port;
   proxy_set_header X-Forwarded-Proto $scheme;
   proxy_set_header X-Forwarded-For $remote_addr;
}

When this is added my sites redirects me to this screen

I have also tried to use =/ in front of the location directive but none of my changes appear to register. Also tried to add this configuration in the Custom locations tab but this shuts down the proxy host.

Adding the lines directly to the proxy_host .conf file causes the proxy_host to go offline.

Nginx Proxy Manager Version
2.11.1

Expected behavior
For the headers to be applied to the location directive without redirecting traffic to the openresty page.

Operating System

Additional context

Same issue here

• image: 'jc21/nginx-proxy-manager:2.10.4'. Works
• image: 'jc21/nginx-proxy-manager:2.11.0' Don't works

@unixweb Did you tested in the version 2.11.1?

[Barrell Titor]

@delsonffilho I can confirm this also happens on 2.11.1. I was pulling my hairs out trying to figure out what I broke

[Delson Filho]

I tested on 2.10.4 and it works.

[thebodzio]

I can confirm the problem with version > 2.10.x (running container from official image on Arch with rootless podman)

Hint: I noticed that whenever I tried to set up a custom location for a proxy host in 2.11.x, the config file associated with the edited host was removed from nginx/proxy_hosts. At the same time entry in database appears to be intact, since the host is still listed and remains editable with no data loss, but goes “Offline” as some previous commenters indicated.

Yes ...

[s0mm3rb]

can confirm 2.10.4 works

custom location in 2.11.1 seems to be broken

[DaRK AnGeL]

can confirm 2.10.4 works

custom location in 2.11.1 seems to be broken

Confirm, same issue with latest version goes back to 2.10.4

[irrwitzer42]

At least for me, 2.11.2 seems to have fixed the issues with custom locations!

2.11.2 not working, send me to openresty

[Muhammad Shah]

Broken for 2.11.1 and 2.11.2 whilst 2.11.1 was fully broken, 2.11.2 now just sends to blank page.
