    This is the nginx.conf file for my external proxy:

    server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;

    server_name ;

    include /config/nginx/ssl.conf;

    location / {
        include /config/nginx/proxy.conf;
        include /config/nginx/resolver.conf;
#        set $upstream_app lemmy;
        set $upstream_app proxy;
        set $upstream_port 8536;
        set $upstream_proto http;
        proxy_pass $upstream_proto://$upstream_app:$upstream_port;
#        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header X-Real-IP $remote_addr;
#        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        client_max_body_size 50M;            
    }
}

access_log /var/log/nginx/access.log combined;

You’ll need to change  to the appropriate value. I’m forwarding requests to the proxy container referenced by the compose file

    My nginx.conf for lemmy-nginx is below, sorry if it’s a bit messy. I prefer to comment than remove working config. You’ll have to change

events {
    worker_connections 1024;
}

#Beginning of kbin fix
# We construct a string consistent of the "request method" and "http accept header"
    # and then apply soem ~simply regexp matches to that combination to decide on the
    # HTTP upstream we should proxy the request to.
    #
    # Example strings:
    #
    #   "GET:application/activity+json"
    #   "GET:text/html"
    #   "POST:application/activity+json"
    #
    # You can see some basic match tests in this regex101 matching this configuration
    # https://regex101.com/r/vwMJNc/1
    #
    # Learn more about nginx maps here http://nginx.org/en/docs/http/ngx_http_map_module.html
    map "$request_method:$http_accept" $proxpass {
        # If no explicit matches exists below, send traffic to lemmy-ui
        default "http://lemmy-ui";

        # GET/HEAD requests that accepts ActivityPub or Linked Data JSON should go to lemmy.
        #
        # These requests are used by Mastodon and other fediverse instances to look up profile information,
        # discover site information and so on.
        "~^(?:GET|HEAD):.*?application\/(?:activity|ld)\+json" "http://lemmy";

        # All non-GET/HEAD requests should go to lemmy
        #
        # Rather than calling out POST, PUT, DELETE, PATCH, CONNECT and all the verbs manually
        # we simply negate the GET|HEAD pattern from above and accept all possibly $http_accept values
