Molti errori su /user-badges.json

Crius · 24 Luglio 2023, 10:16am

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

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

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

Cheers!

Nel caso possa essere d’aiuto, e sperando che non sia sgradito, ecco uno snapshot di quel thread, che conta 185 post:

Grazie @Ed_S, finché l’hostname non è in chiaro va tutto bene, semplicemente non voglio che bot/wannabe hacker se la prendano troppo comoda e si divertano un po’ con un piccolo forum della community.

Sto già dedicando troppo tempo rispetto a quanto mi aspettassi, per questo

hello-smile6 · 25 Luglio 2023, 12:53am

Sembra che tu stia utilizzando la funzionalità di proxy inverso HTTP di Cloudflare ma non hai configurato nginx per utilizzare gli IP reali che i server Cloudflare inviano per le richieste, il che potrebbe causare problemi (se ogni richiesta sembra provenire dalla stessa origine, tutti i tuoi utenti saranno interessati dai limiti di velocità, anche se solo uno sta inviando richieste eccessive)

Crius · 28 Luglio 2023, 10:06pm

Grazie per l’indizio, hai qualche argomento/guida che potrei leggere su come risolvere questo problema?

Il reverse proxy è stato una richiesta da chi possiede effettivamente il VPS per non esporre l’IP effettivo.

hello-smile6 · 29 Luglio 2023, 3:52am

Aggiungere quel template lo fa funzionare correttamente?

Crius · 29 Luglio 2023, 10:02pm

Ricostruzione in corso. Lo lascerò in esecuzione per tutta la notte e controllerò domani/lunedì (sono ancora nel bel mezzo del trasloco e dello spacchettamento )\n\nModifica: Un rapido controllo subito dopo la ricostruzione sembra aver risolto il problema \n\nAggiornerò comunque tra un paio di giorni!

Crius · 19 Agosto 2023, 4:10pm

“Un paio di giorni dopo”: sì, abilitare il template aggiuntivo per Cloudflare ha risolto il problema delle richieste di badge non riuscite.

Sono stati risolti anche altri problemi, come il filtro IP per amministratori/moderatori che mostrava tutti provenienti dallo stesso IP.

Tuttavia, il monitoraggio che ottengo dagli scrape di Prometheus mostra comunque molti errori.
Dovrò trovare del tempo per esaminare i log di nginx, immagino.
