Troubleshooting a 429 (rate limit)

Coming back to this Topic as the other one is slightly different.

Do we still need to be doing something like in the post above?

Looking through the /etc/nginx/conf.d/discourse.conf file there seems to be no mention of set_real_ip_from (searching the Discourse repo for the same yields no results either). From the discourse.conf file these seem most relevant:

(mentions of IP)

    # This big block is needed so we can selectively enable
    # acceleration for backups and avatars
    # see note about repetition above
    location ~ ^/(letter_avatar/|user_avatar|highlight-js|stylesheets|favicon/proxied|service-worker) {
      proxy_set_header Host $http_host;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Request-Start "t=${msec}";
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header X-Forwarded-Proto $thescheme;

    # we need buffering off for message bus
    location /message-bus/ {
      proxy_set_header X-Request-Start "t=${msec}";
      proxy_set_header Host $http_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 $thescheme;
      proxy_http_version 1.1;
      proxy_buffering off;
      proxy_pass http://discourse;
      break;
    }

    # auth_basic on;
    # auth_basic_user_file /etc/nginx/htpasswd;

    location ~* (assets|plugins|uploads)/.*\.(eot|ttf|woff|woff2|ico)$ {
      expires 1y;
      add_header Cache-Control public,immutable;
      add_header Access-Control-Allow-Origin *;
     }

    location = /srv/status {
      access_log off;
      log_not_found off;
      proxy_set_header Host $http_host;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Request-Start "t=${msec}";
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header X-Forwarded-Proto $thescheme;
      proxy_pass http://discourse;
      break;
    }

Which appear to be setting the correct remote address :confused:

For completeness I received a couple of 429s after a peak in traffic a couple of days ago, and looking at my app.yml I found that the set_real_ip_from my.server.ip; and real_ip_header CF-Connecting-IP; lines were commented out… but it doesn’t look like they do anything anyway? Can you remember what the outcome of your investigations were after?

Currently I am recommending adding those lines to the app.yml in the following guide: How to set up Discourse on a server with existing Apache sites (and so may be giving bad advice to others?)
