Gran cantidad de errores en /user-badges.json

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!

Por si sirve de ayuda, y esperando que no sea inoportuno, aquí tenéis una instantánea de ese hilo, que tiene 185 publicaciones:

Gracias @Ed_S, siempre que el nombre de host no esté en texto plano, todo está bien. Simplemente no quiero que los bots/aspirantes a hackers se lo pongan demasiado fácil y se diviertan un poco con un pequeño foro comunitario.

Ya estoy dedicando demasiado tiempo en comparación con lo que esperaba, para ello

Parece que está usando la función de proxy inverso HTTP de Cloudflare, pero no tiene nginx configurado para usar las IP reales que los servidores de Cloudflare envían para las solicitudes, lo que podría causar problemas (si cada solicitud parece provenir de la misma fuente, todos sus usuarios se verán afectados por los límites de velocidad, incluso si solo uno está enviando solicitudes excesivas).

Crius · 28 Julio, 2023 22:06

Gracias por la pista, ¿tienes algún tema/guía que pueda leer sobre cómo solucionar esto?

El proxy inverso ha sido una solicitud de quien realmente posee el VPS para no exponer la IP real.

¿Añadir esa plantilla hace que funcione correctamente?

Crius · 29 Julio, 2023 22:02

Reconstruyendo ahora. Lo dejaré funcionando durante la noche y volveré a revisar mañana/lunes (todavía estoy en medio de la mudanza y desempaquetando )\n\nEditar: Una rápida comprobación inmediatamente después de la reconstrucción parece haber resuelto el problema \n\n¡Actualizaré en un par de días de todos modos!

Crius · 19 Agosto, 2023 16:10

«Un par de días después»: sí, habilitar la plantilla adicional para Cloudflare resolvió el problema de que esas solicitudes de insignias fallaran.

También se resolvieron otros problemas, como el filtro de IP para administradores/moderadores que mostraba a todos viniendo de la misma IP.

Sin embargo, el monitoreo que obtengo de los scrapes de Prometheus muestra muchos errores de todos modos.
Tendré que encontrar algo de tiempo para revisar los registros de nginx, supongo.
