Looking for help in docker installation of Lemmy

I followed the docker installation instructions and added the certificate successfully but I get this status:

400 Bad Request | nginx

host nginx error logs:

I replaced my host IP and domain for privacy

Please see my comments below for more info. I tried putting all text here in the body but it won't let me post.

EDIT: It is now fixed! What I did is replace the following line in my host nginx:

location / {
         proxy_pass http://localhost:82;
         proxy_set_header Host $host;  <---- replace this
         include proxy_params;
    }

With this:

location / {
         proxy_pass http://127.0.0.1:82;
         proxy_set_header Connection "keep-alive, Upgrade";
         proxy_set_header Upgrade websocket;
         include proxy_params;
    }

And thanks to @[email protected] who pointed me in the right direction to allow search to other instances:

networks:
  # communication to web and clients
  lemmyexternalproxy:
  lemmybridge:  <<----- added this
  # communication between lemmy services
  lemmyinternal:
    driver: bridge
    internal: true

services:
  proxy:
    image: nginx:1-alpine
    networks:
      - lemmyinternal
      - lemmyexternalproxy
      - lemmybridge  <<----- added this

  lemmy:

Comment out proxy_set_header Host $host; and sudo systemctl reload nginx.
