We just deployed the latest version of Lemmy 0.19.2 where the github code includes a possible fix for the outgoing federation issues we have been having.

But lets see before we celebrate. Help us test if outgoing federation seems to work now by making comments, posts and upvotes and see if they appear on other instances.

Of course if the other instances are on Lemmy 0.19.0 or 0.19.1, they could have issues with outgoing federation still until they update.

My apologies. This may just be a combination of an error on my part and Lemmy not working as I had thought it worked.

There are two retrogaming communities, one on lemmy.world and one on kbin.social. I had thought that I was subscribed to both, but I was only subscribed to the one on kbin.social. lemmy uses subscriptions to determine whether to cause posts to propagate.

What I still don't understand is why being logged is a factor. I definitely could see the posts when not logged in, so they made it to lemmy.today.

I just subscribed with my lemmy.today account, made a post with another account (on kbin.social), then unsubscribed and made another post with that second account. Both posts were visible to my account.

So I still don't understand why being logged in is a factor for the earlier posts, but at the time that I was seeing the problem, I wasn't subscribed, and lemmy doesn't guarantee that propagation happens in that scenario, so I'm not going to complain about that.

thinks

Maybe when you browse a remote community not logged in -- since it's not possible for a guest user to subscribe -- lemmy fetches the posts directly when the community is viewed, rather then having them pushed to it. Otherwise, it wouldn't be possible to do much as a guest user with remote communities. And if nobody on lemmy.today was subscribed, that would explain the lack of popagation. That'd produce that behavior, where a guest user can see posts, but a logged-in user can't unless they're subscribed.

I don't know why different logged-in accounts would see different sets of posts, but.

Well, I'm sorry for bothering you. Probably just user error, and me being too ready to flag something as a bug after seeing earlier federation breakage. Thanks for your time.

Its ok, Im happy if you find a bug in Lemmy so we can report it to the developers. There are many bugs on their github issues page, so I wouldnt be surprised if you encounter some.. :)
