Not sure if this is the same problem, but it has been noticed that passing messages between federated instances has been hampered by the way the “worker threads” are currently been done. The big instances are essentially getting overloaded with outbound federation work. Solutions for that are in the works. issue/3230

Yeah, it’s definitely annoying, but if it’s any consolation, it’s a system-wide problem. Not sure if/when/how they fix, but if this place is going to be a long term Reddit replacement, I feel like they’re going to have to.

I had a similar problem that ended up having to do with my server’s language settings. I didn’t realize you can select more than just “Undetermined” by holding down shift or ctrl. So everything tagged as English didn’t appear until I went back and fixed it. You can read the whole odyssey here: https://lemmy.ml/post/1205767

Hopefully it’ll mostly resolve given time. Just like when there was a mass exodus to mastodon, the major thrediverse servers are getting overloaded. This creates delays and it seems even lost messages. From experience I’ve had messages from fedia.io take anywhere from 20-120 minutes to show up on my mastodon. As admins beef up their servers, but also as excitement tones down and there is less enthusiastic usage, hopefully the problem will resolve for the most part.

I’m not sure what causes messages to be lost forever vs. just delayed. Maybe Kbin or Lemmy aren’t quite as robust in that? When mastodon was melting down, messages could take 8+ hours to get through, but they seemed to get through. I think your idea about a resync idea is a great one.

I’m glad I’m not the only one. I am commenting on this post from my own instance and it says it has 0 replies which I know is wrong. I did only federate with Selfhosted just a few hours ago. Who know how long it will take this post to get back to lemmy.world.

I have the same issue. I use multiple accounts across different servers, and get a different subset of comments across each one. Not sure the solution right now.

Upvoting since I plan to run my own Lemmy instance too. Would be interested in force-sync

Thanks for pointing this out, I am just now realizing I am also missing comments. For example this post, I have 7 comments, but the actual post has 10.

Yep, it’s because of the volume of comments/posts going through the big instances right now, and how many people are subscribed outside of those instances. It’s too much for the server to keep up. I noticed over the last day or two my feed has mostly been Beehaw.org stuff because they don’t seem to be having as hard of a time. It sure is looking like we need more separation like startrek.website, and maybe it was a bad idea to allow communities to just be made by anyone on lemmy.world and sh.itjust.works. Would’ve made more sense for all the users to be on these instances, but the communities hosted elsewhere.

I’m seeing this issue primarily with communities hosted on lemmy.ml and lemmy.world. Admittedly, that’s a lot of the active ones at the moment, but for some of the smaller ones I follow, they seem to show up.

Try upping your federation workers

Its likely not a fault on your end, but overloaded servers on the other side failing to push updates or pushing them more that 10 seconds delayed after which your instance will discard them.

The latter part could be improved in the codebase I guess, but overloaded severs are just a reality right now, especially lemmy.ml

I believe the solution is to wait until 0.18 is released and everyone updates to it.

i am preparing to launch my own (likely single-user) instance and i’m not sure if i should wait until 0.18 proper or just throw the rc and see if that’s enough.

I have the same issue. Comments on some posts dont seem to update at all for me
