The nginx default for [client\_max\_body\_size](https://nginx.org/en/docs/http/ngx_http_core_module.html#client_max_body_size) is 1MB, client-side rescaled jpegs are all under 1MB, everything become clear.

I fixed my nginx config: [Set client\_max\_body\_size to 4m to match Discourse configuration. · AFPy/infra@861af29 · GitHub](https://github.com/AFPy/infra/commit/861af29c7d7244d8ed3b2cb068a3f047171d4659)

And it now works. You were right: it was my reverse proxy.

Thank you all ❤ and sorry for the noise!
