It seems that federation between Lemmy and Kbin is broken again. For some reason, it is still possible to connect to communities that was connected before federation broke, but not newer communities:
Works
https://kbin.social/m/selfhosted@lemmy.world
Doesn't work
https://kbin.social/m/xcode@lemmy.world
It is a bit different though, I can search for xcode@lemmy.world and actually find it: https://i.imgur.com/Pf7k3jO.png
Now that I've actually searched for it once the page you linked should actually start working too instead of throwing a 404.
This never happens with guildwars2@lemmy.wtf, search always returned nothing. It really looks like something specific between lemmy.wtf and kbin.social.
May this still be caused by the Cloudflare Challenge as pointed out in the following lemmy issue on GitHub or has this been solved already?
https://github.com/LemmyNet/lemmy/issues/3020
Would it matter when you are trying to reach lemmy.wtf from kbin.social? The Cloudflare Challenge shouldn't do anything for outgoing from Kbin.social.
I use Cloudflare and Cloudflare Tunnel for lemmy.wtf as well, so maybe Cloudflare is blocking Kbin.social's request?
As far as I understand you are both using Cloudflare and I assume that the Cloudflare Challange only hits incoming connections, but I have no practical experience with Cloudflare myself.
Anyway, when both
lemmy.wtf
as well askbin.social
are using Cloudflare, then traffic is always incoming via Cloudflare whenever those instances are trying to communicate/federate with each other.I've found posts which suggest to exclude certain paths/URLs from bot detection thereby suppressing the Challenge when a bot does what a bot is supposed to do, but there also appears to be an Essentially off setting which one could try temporarily to see whether this solves the issue.
Looks like
kbin.social
's IP is registered on Cloudflare's DNS servers, but the IP belongs to Fastly.Maybe running a lemmy or kbin instance behind Cloudflare isn't such a good idea after all. Apart from communication problems like federation not working properly there are some serious privacy concerns or rather running federated network traffic through a centralized US based network service kinda contradicts the whole fediverse idea.
Yes, I believe cloudflare blocks federation.
Only between kbin and Lemmy, but why?
I don't know. Some people over in the kbinmeta group might have an answer for you. I just know that when kbin had cloudflare turned on we couldn't communicate with anyone outside of kbin.
I am now able to find https://kbin.social/search?q=guildwars%40lemmy.wtf but not https://kbin.social/search?q=guildwars2%40lemmy.wtf
That makes zero sense...
I can see both communities now.
Yes, it it finally working now :D
https://kbin.social/m/guildwars2@lemmy.wtf
Only issue is the delay, but I am thinking this is because kbin.social is strained from all the new users.
