I am trying to follow !tenforward@lemmy.world from my self hosted instance. When I search for it on my instance (with the "All" tab selected) I get no results found. When I go to the community https://lemmy.world/c/tenforward, click subscribe, enter my instance name, I'm redirected back to my instance, but there's a "Cannot fetch !tenforward@lemmy.world" error in the UI, and in my server logs I see this:

     The webfinger object did not contain any link to an activitypub item

Lemmy Server Version

Lemmy Instance URL

lemmy.cringecollective.io

This is only happening for some communities, for example, subscribing to this community worked fine, and I was able to subscribe to other communities on lemmy.world. (3dprinting@lemmy.world worked fine)

Any ideas why this is happening? Is this on my end?
