Working configuration for the new Vaultwarden reverse proxy settings?

[Hobbabobba]

Vaultwarden changed the settings for the reverse proxy configuration.

The example for the new nginx configuration is

# The `upstream` directives ensure that you have a http/1.1 connection
# This enables the keepalive option and better performance
#
# Define the server IP and ports here.
upstream vaultwarden-default {
  zone vaultwarden-default 64k;
  server 127.0.0.1:8080;
  keepalive 2;
}

# Needed to support websocket connections
# See: https://nginx.org/en/docs/http/websocket.html
# Instead of "close" as stated in the above link we send an empty value.
# Else all keepalive connections will not work.
map $http_upgrade $connection_upgrade {
    default upgrade;
    ''      "";
}

# Redirect HTTP to HTTPS
server {
    listen 80;
    listen [::]:80;
    server_name vaultwarden.example.tld;

    if ($host = vaultwarden.example.tld) {
        return 301 https://$host$request_uri;
    }
    return 404;
}

server {
    # For older versions of nginx appened http2 to the listen line after ssl and remove `http2 on`
    listen 443 ssl;
    listen [::]:443 ssl;
    http2 on;
    server_name vaultwarden.example.tld;

    # Specify SSL Config when needed
    #ssl_certificate /path/to/certificate/letsencrypt/live/vaultwarden.example.tld/fullchain.pem;
    #ssl_certificate_key /path/to/certificate/letsencrypt/live/vaultwarden.example.tld/privkey.pem;
    #ssl_trusted_certificate /path/to/certificate/letsencrypt/live/vaultwarden.example.tld/fullchain.pem;

    client_max_body_size 525M;

    location / {
      proxy_http_version 1.1;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection $connection_upgrade;

      proxy_set_header Host $host;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header X-Forwarded-Proto $scheme;

      proxy_pass http://vaultwarden-default;
    }
}

Since there are some settings outside of the location block, I have to idea how to get this working via advanced configuration.
Anyone has an idea?

It works fine by default. ( I am using this myself, and removed the separate websocket port)
Vaultwarden made this easier. Instead of a separate websocket listener now all works on 1. So your config is even more simplified.
It is all about the websocket support, and nginx-proxy respects this by default.

Keepalive is not required for Vaultwarde, but if you want to enable it: Upstream (Backend) Server HTTP Keep-Alive Support
