Discourse 설정을 시도 중인데 SSO 때문에 사용할 수 없나요?

Discourse 사이트를 설정하고 있습니다. NGINX를 통해 라우팅이 되고 있습니다.

enable_discourse_id: Discourse ID에 자동으로 등록하지 못했습니다. 이는 네트워크 연결 문제, 방화벽 제한 또는 Discourse ID 서비스에 도달할 수 없기 때문일 수 있습니다. 자세한 내용은 서버 로그를 확인하거나 지원에 문의해 주세요.

이메일 설정을 현재 건너뛰기로 선택하셨습니다. 불행히도 위의 오류 메시지로 인해 설정을 계속할 수 없습니다. 이 문제를 meta.discourse.org에 보고해 주세요.

제 NGINX 설정입니다. SSO가 깨지는 것이 무엇인지 확실하지 않습니다.

web.socketed.template.yml에서 가져온 유닉스 소켓 포트도 사용해 보았습니다.

제 app.yml 설정입니다.

## this is the all-in-one, standalone Discourse Docker container template

## After making changes to this file, you MUST rebuild
## /var/discourse/launcher rebuild app
##
## BE *VERY* CAREFUL WHEN EDITING!
## YAML FILES ARE SUPER SUPER SENSITIVE TO MISTAKES IN WHITESPACE OR ALIGNMENT!
## visit http://www.yamllint.com/ to validate this file as needed

templates:

## which TCP/IP ports should this container expose?
## If you want Discourse to share a port with another webserver like Apache or nginx,
## see https://meta.discourse.org/t/17247 for details
expose:
  - "4180:80" # http
#  - "443:443" # https

params:
  db_default_text_search_config: "pg_catalog.english"

  ## Set db_shared_buffers to a max of 25% of the total memory.
  ## will be set automatically by bootstrap based on detected RAM, or you can override
  #db_shared_buffers: "256MB"

  ## can improve sorting performance, but adds memory usage per-connection
  #db_work_mem: "40MB"

  ## Which Git revision should this container use? (default: latest)
  #version: latest

env:
  LC_ALL: en_US.UTF-8
  LANG: en_US.UTF-8
  LANGUAGE: en_US.UTF-8
  # DISCOURSE_DEFAULT_LOCALE: en

  ## How many concurrent web requests are supported? Depends on memory and CPU cores.
  ## will be set automatically by bootstrap based on detected CPUs, or you can override
  UNICORN_WORKERS: 3

  ## TODO: The domain name this Discourse instance will respond to
  ## Required. Discourse will not work with a bare IP number.
  DISCOURSE_HOSTNAME: "forum.website.net"

  ## Uncomment if you want the container to be started with the same
  ## hostname (-h option) as specified above (default "$hostname-$config")
  #DOCKER_USE_HOSTNAME: true

  ## uncomment to set the port to something other than the default (25)
  #DISCOURSE_SMTP_PORT: 587
  ## USER_NAME / PASSWORD required if the SMTP provider needs authentication
  ## WARNING: a '#' in the SMTP password can be misinterpreted; ensure it's inside string quotes, e.g.:
  ##   DISCOURSE_SMTP_PASSWORD: "#pass#ord"
  # DISCOURSE_SMTP_USER_NAME: user@example.com
  # DISCOURSE_SMTP_PASSWORD: "pa$$word"
  ## uncomment to enable implicit TLS at connection time, probably needed for using port 465

## The Docker container is stateless; all data is stored in /shared

## Plugins go here
## see https://meta.discourse.org/t/19157 for details
hooks:
  after_code:
    - exec:
        cd: $home/plugins
        cmd:
          - git clone https://github.com/discourse/docker_manager.git

## Any custom commands to run after building
run:
  - exec: echo "Beginning of custom commands"
  ## If you want to set the 'From' email address for your first registration, uncomment and change:
  ## After getting the first signup email, re-comment the line. It only needs to run once.
  #- exec: rails r "SiteSetting.notification_email='info@unconfigured.discourse.org'"
  - exec: echo "End of custom commands"

이 문제를 어떻게 수정할 수 있는지 아는 분이 있을까요? 또한, 당분간 이메일 로그인/로그인을 사용하지 않을 예정입니다. 따라서 SSO만 사용하려고 합니다.

어떤 호스팅 제공업체를 사용하고 계신가요? Discourse 사이트가 브라우저에서 접근 가능한 상태인가요?

저는 호스틴저(Hostinger)를 사용하는데, 접속은 가능하지만 SSO가 작동하지 않아서 로그인하거나 사용할 수 없습니다.
