My main account is [email protected]. However, as of roughly 24-hours ago (it seems this has been going on since March 10th and gotten worse since) it seems like the server has stopped properly retrieving content from lemmy.world.
It’s been running smoothly for well over 9 months, and (I think) working fine for content coming in from other instances. So I’m curious if anyone else experienced anything strange with lemmy.world federation recently?
Setup Description
The server flow in my case is as follows:
[Public Internet] <-> [Digital Ocean Droplet] <-> [ZeroTier] <-> [Physical Machine in my Basement (HW Info)]
The Digital Ocean droplet is a virtual host machine that forwards requests via nginx to the physical machine where a second nginx server (running the standard lemmy nginx config) then forwards the request to the lemmy server software itself.
Current Status
Lemmy Internal Error
I’ve found this is my lemmy logs:
2024-03-24T00:42:10.062274Z WARN lemmy_utils: error in spawn: Unknown: Request limit was reached during fetch
0: lemmy_apub::objects::community::from_json

at src/root_span_builder.rs:16
I’m thinking this could be the cause … though I’m not sure how to raise the limit (it seems to be hard coded). I opened an issue with the Lemmy devs but I’ve since closed it while gathering more information/making sure this is truly an issue with the Lemmy server software.
Nginx 408 and 499s
I’m seeing the digital ocean nginx server reporting 499 on various “/inbox” route requests and I’m seeing the nginx running on the physical machine that talks directly to lemmy reporting 408 on various “/inbox” route requests.
There are some examples in this comment: https://lemmy.world/comment/8728858
Here’s a handy site to check your federation status: https://phiresky.github.io/lemmy-federation-state/site?domain=social.packetloss.gg
It looks like all the sites are lagging, which can sometimes mean there is an issue. What’s the specs of the server? Can you try restarting it and seeing if that helps?
There are issues for servers hosted in places like Australia because of the latency in communicating with .world due to how big it is and how much data it sends because of this.
This is the right answer
I’m not having issues that I’m aware of, but that site always returns Network Request Failed and I haven’t figured out why.
So, I think this is a (helpful) general comment but wrong in this/my specific case.
The server is so small it’s not really going to register on a 10-minute frequency for outgoing content – I’m not that much of a lemmy addict! haha.
You can see in a comment here my most recent comment to lemmy.world did sync: https://lemmy.world/comment/8728858
I’m not having any issues with outgoing content, beehaw, the KDE instance, and several others. It’s just lemmy.world that’s acting up (which is unfortunately because it’s my favorite – I mod/run several communities and donate to here/them – haha).
