Here I am again pestering you guys.

Our users are formed by a good amount of tech-savvy people and raised this issue that I’ve had spotted some time ago but decided to postpone as I am also busy with non-forum-admin stuff :roll_eyes:

Anyway, today is a day in which I have people packing our house before a move so I can’t work anyway.

It’s quite some time that I noticed this but I can’t figure out why it’s happening only for the specific endpoint that return the badges for users.

I’ve a 224k rows logs I can pass along to support if needed but an excerpt that summarize it can posted here:

OMITTED.COM is of course not the real hostname :stuck_out_tongue:

This is what the prometheus metrics are showing me as well, which is imho a number of error requests that is definitely too high.

I thought of the rate limits but it’s happening only for that specific endpoint (I mean, significantly more at least) and if it was a rate limit issue wouldn’t it have to happen on other GET(s) as well?

I’m trying to understand what could be causing this first of all. Any hint or further info request is appreciated.

Just be aware I may be not that responsive this week as I’m literally moving house in the next 3-4 days :weary:

Cheers!

@Ed_Sさん、ありがとうございます。ホスト名が平文でなければ問題ありません。単に、ボットや「なりすましハッカー」が簡単にアクセスして、小さなコミュニティフォーラムで「楽しむ」ことを避けたいだけです。

すでに予想以上に多くの時間を費やしています。:laughing:

CloudflareのHTTPリバースプロキシ機能を使用しているようですが、Cloudflareのサーバーがリクエストに対して送信する実際のIPを使用するようにnginxが設定されていないようです。これは問題を引き起こす可能性があります（すべてのリクエストが同じソースから来ているように見える場合、1人のユーザーが過剰なリクエストを送信しても、すべてのユーザーがレート制限の影響を受けます）。

ヒントをありがとうございます。これを修正する方法について、何か読めるトピックやガイドはありますか？

リバースプロキシは、実際のIPアドレスを公開しないようにVPSの所有者からリクエストされたものです。

そのテンプレートを追加すると正しく機能しますか？

再構築中です。一晩実行して、明日か月曜日に確認します（まだ引っ越し荷解きの最中です :weary:）

編集：再構築直後に簡単な確認をしたところ、問題は解決したようです :+1:

数日中に改めて報告します！

「数日後」：はい、Cloudflare の追加テンプレートを有効にすることで、バッジリクエストの失敗の問題が解決しました。

また、管理者/モデレーターの IP フィルターが全員同じ IP から来ているように表示されるなどの他の問題も解決しました。

ただし、Prometheus のスクレイプから得られる監視では、とにかく多くのエラーが表示されています。
nginx のログを調べる時間を確保する必要があるでしょう。
