you are accessing the Lemmy admin page through the official Lemmy UI, correct?

Correct.

do you mind sharing (if there are any) error logs of the Lemmy backend?

I’ve got no “error” lines, but outside of “trace”, “debug” and “info”, I have the following “warn” line :

2025-07-29T23:34:21.058352Z  WARN Error encountered while processing the incoming HTTP request: pan_builder: InboxTimeout: InboxTimeout
   0: lemmy_server::root_span_builder::HTTP request
           with http.method=POST http.scheme="https" http.host=blog.kaki87.net http.target=/inbox otel.kind="server" d432-40fa-a865-6690f61e11dc http.status_code=400 otel.status_code="OK"
             at src/root_span_builder.rs:16

Btw you might want to close the registrations. They are open right now.

Indeed, which is weird, because I’m sure I closed them when I first created the instance. Are settings lost during upgrades ?

Go to the admin page in the lemmy UI and turn on federation. If you selected “Allowlist” or “Blacklist”, select “Open” as the federation mode.

All I see is a “Federation enabled” checkbox that is checked, an “allowed instances” list that is empty, a “blocked instances” list that is empty as well, and a “federation debug mode” checkbox that is unchecked.

I don’t see “allowlist”, “blocklist” or “federation mode”.

Thanks

Check the logs and config.

What should I be looking for ?

How to fix this though ?

D’où vient cette citation, et quel est le contexte ?

Hé ben merde alors, c’était le meilleur client Lemmy.

So, here’s the full error :

lemmy-1  | 2025-07-14T00:34:32.098630Z DEBUG HTTP request{http.method=POST http.scheme="https" http.host=blog.kaki87.net http.target=/inbox otel.kind="server" request_id=a9c359f6-eb9d-4888-9ac2-55c1f5bb8e43}: actix_web::middleware::logger:

I’ve also been seeing this one :

lemmy-1  | 2025-07-14T00:41:00.407762Z DEBUG HTTP request{http.method=GET http.scheme="http" http.host=lemmy:8536 http.target=/api/v3/site otel.kind="server" request_id=9aab8319-3f3b-4f4e-8530-3b3633afe2f1}: actix_web::extract: Error for Option<T> extractor: IncorrectLogin: IncorrectLogin

As for the reverse proxy, I’m using Caddy with the configuration provided here, and it’s supposed to pass those headers by default.

The suggested curl requests work.

I wish there was a tool that could just tell what’s wrong, like https://federationtester.matrix.org/ for Matrix…

What am I looking for in the logs though ? All I see is “InboxTimeout”…

I left a comment on your server but it doesn’t seem to be federating

Oh, no ! I’ll have to look into that, thank you for noticing ! Any ideas how to debug that ?

Terribly sorry about nerd sniping you!

No problem haha, I’ve been wanting this for a while already ^^

An easy way to fast track federation is using lemmy-federate.

Interesting !

Anyway, best of luck on your blog. If you’ve questions or want to discuss, feel free to send me a message!

Thanks again !

Parce-que si tu as plusieurs toi, alors tu peux combattre en équipe, donc avec une stratégie différente que si toi est seul

Tu demandes pour un toi ?

Combien de toi as-tu ?

That works, thanks !

For anyone else encountering the same issue as me, here are the steps to perform beforeand for this to work :

• Add the widget to both panels and edit settings as follows for both panels ;
• Check Appearance ➔ Panel customization ;
• Check Appearance ➔ Color ➔ Enable ;
• (If you wanna preserve the closed to original color) Check Appearance ➔ Color ➔ System & select Color set ➔ Window.

Oh I didn’t notice your answer, yeah I figured the same, so I changed the links to lemmyverse.link instead.

Oh I see, it’s Lemmy previewing the crosspost instead of redirecting to it.

I fixed it now.

Je regarderai, merci !

Actual pattern-matching allows matching on the structure of a data type

That’s a condition, so it can fit in a ternary.
