我在使用jwilder/nginx-proxy和cloudflare ssl（origin key，FULL type SSL）时遇到问题。
一切正常（在http中），直到我激活Cloudflare的DNS代理。服务器返回521（Web服务器关闭）。
这是我的docker-compose.yaml

version: "2"

services:
  nginx-proxy:
    image: jwilder/nginx-proxy:alpine
    ports:
      - 80:80
    volumes:
      - /var/run/docker.sock:/tmp/docker.sock:ro
      - ./certs:/etc/nginx/certs
    network_mode: bridge

  saraswati-global:
    image: asia.gcr.io/ordent-production/ordent/saraswati-global
    ports:
      - 3000:3000
    environment:
      - VIRTUAL_HOST=beta.saraswati.global
      - VIRTUAL_PORT=3000
      - VIRTUAL_PROTO=https
    network_mode: bridge

  api-healed-id:
    image: asia.gcr.io/ordent-production/ordent/api.healed.id
    ports:
      - 4001:4001
    environment:
      - VIRTUAL_HOST=dev.healed.id
      - VIRTUAL_PORT=4001
      - VIRTUAL_PROTO=https
    network_mode: bridge

或许你们能帮我配置一下-
下面是上面的配置创建的nginx配置：

# If we receive X-Forwarded-Proto, pass it through; otherwise, pass along the
# scheme used to connect to this server
map $http_x_forwarded_proto $proxy_x_forwarded_proto {
  default $http_x_forwarded_proto;
  ''      $scheme;
}
# If we receive X-Forwarded-Port, pass it through; otherwise, pass along the
# server port the client connected to
map $http_x_forwarded_port $proxy_x_forwarded_port {
  default $http_x_forwarded_port;
  ''      $server_port;
}
# If we receive Upgrade, set Connection to "upgrade"; otherwise, delete any
# Connection header that may have been passed to this server
map $http_upgrade $proxy_connection {
  default upgrade;
  '' close;
}
# Apply fix for very long server names
server_names_hash_bucket_size 128;
# Default dhparam
ssl_dhparam /etc/nginx/dhparam/dhparam.pem;
# Set appropriate X-Forwarded-Ssl header
map $scheme $proxy_x_forwarded_ssl {
  default off;
  https on;
