I set up a self-hosted instance yesterday, so far it runs fine. I can subscribe from there to communities hosted on other instances, I can comment from my instance and the comments show up on other instances.
However, I subscribed to https://lemmy.world/c/lemmyworldtest from my own instance to test if my posts will be propagated, and that seems not to work (yet?).
Is this a known problem? Would the upstream instance subscribe to my instance for this to work? Or is this a bug in my configuration?
pretty sure you webfinger resolve the community and it gives you an inbox for activitypub that you publish to. Everything is push, nothing is pull.
and i’m pretty sure that when the community receives the post, it then pushes it to all the subscribers.
Hmm, I may need to freshen up my understanding of ActivityPub dynamics
