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.
Hmm, I may need to freshen up my understanding of ActivityPub dynamics
