Why do some instances not load communities properly? (lemmings.world)

I just started my own Lemmy instance, and it looks to be mostly working.

The problem that I have is that the communities I went through the process of subscribing to only display up to 50 threads and no comments.

This looks like something I've seen on other servers, so I'm wondering what could be causing it and how to fix it.

ChatGPT says something about webfinger and nodeinfo, but I honestly have no idea what any of that is and there's no mention of it in https://join-lemmy.org/docs/administration/federation_getting_started.html

That is how federation works. You will not get all content automatically, only the ones you wish for.

When you subscribe to a new community (as in your instance hasn't "seen" it yet), it will fetch the last 20 posts. (excluding votes and comments)

If you wish to see older comments and posts, you must fetch them manually. You can see how that can be done here: https://join-lemmy.org/docs/administration/federation_getting_started.html

Usually Lemmy/piefed does a pull of the most recent 50 posts when the follow first happens. Then new posts come in over time via federation.

If you're not getting /any/ new posts it may be that the federation is not working. If some communities gets posts more than others then it's probably a difference in activity levels in the communities.

Is it just a sync thing, and more will come in over time? I've never played with hosting. But I do know you should check the logs.

blackfox@lemmings.world 50 threads, as in they go to 50 and stop getting new ones?

The outbox on a Lemmy community only has the last 50 posts and there is no pagination to get another 50. Also Lemmy posts have no replies collection so it's impossible to get the replies without using their API.
