The servers need a bit of time to sync up, especially with these new communities. I am keeping a small text doc to try again later with when they don't work. The more people participate, the more the servers will "talk" and sync. It's early growing pains. I noticed it on Mastodon, but it sped up after more people joined.

It doesn't for me (from lemmy.sdf.org). Odd thing going on here.

In general with Lemmy I don't understand why links to communities can't open in your local webapp. The little dance of navigating through search seems like it shouldn't be necessary technically.

Is it possible the community is literally named that with the @ suffix included? And that confuses other Lemmy instances?
