The communities have to get cached from your local instance. And sometimes it takes some time. I would suggest to search for it directly. And it looks like the url u send works now.
Still returning 404 for me and searching directly on kbin doesn't give me results, sadly. Could it be also an issue with caching on my end? Like, do I need to clear cache and cookies? Would be odd, but I don't want to dismiss it as a requirement.
Now I can subscribe, but it's still empty, but it's not 404 anymore. Now I can access it through the link as well. Man, this federation stuff still is a bit midn-boggling despite being such a simple concept. Devil is in the details.
Wait for the instance to start caching content from the comm. It might even take a few days, but eventually, it will start caching. Sometimes it might lag though, like cache for a day or two, than stop for a day or two, than catch up... these are all home servers or VPSes, they're not as powerfull as the servers corps have at their disposal 🤷.
Yeah, that makes some sense. Seeing the community also says created by Ernest and like half an hour ago or so. Seems to me the instance creates a local copy, once it's first accessed (or automatically found) and that has to be cached periodically. Slowly starting to click together, how it all works.
