I subscribed to communities, but my Lemmy instance receives only a few posts, comments and votes. I can see linked instances, but whether or not they sync data feels hit or miss. I’m not quite sure if this is expected. Does Lemmy have a utility similar to the Matrix federation tester?
Are you on a private instance? It can take a long while for your instance to catch up to current stuff.
As far as testing federation… you posted to lemmy.ml from your instance… federation is working :)
Something is seriously wrong. It’s been hours and I looked at 7 or 8 instances, nobody has a complete copy. Your instance only shows your own comment: https://lemmy.saik0.com/post/4283
The comment you are reading is comment #14 on lemmy.ml
Well it’s possible that an instance blocks other instances. This also includes things like firewalls and proxy services. I for instance block all Russian and Chinese ip addresses outright. I want nothing to do with either of those countries from a web perspective. It’s possible that on their instance they’re blocking my instance, or IP so it’s not quite populating properly. There’s a lot that can go wrong… Doesn’t help that lemmy.ml is getting HAMMERED recently.
Actually looking at their instance… They’re using Cloudflare (I see the email protection injected code). Cloudflare in particular likes to mark ActivityPub traffic as “bot” traffic and block it. It’s more likely that lemmy.ml is blocked for that particular instance by cloudflare. Smaller instances like mine probably don’t get flagged. So it shows up in their instance just fine… https://lemmy.haigner.me/post/8?scrollToComments=true
But other instances might have problems talking to them. They need to setup a page rule to allow lemmy traffic through cloudflares bot detection.
