Weird, It shows up for me: https://lemmy.studio/...

actually, I just noticed this community doesn't show up in the community browser - https://browse.feddit.de/

I'd guess it's not federated, meaning the instance where the community was created is not configured to allow subscription access from other instances, but you can access it by reaching that instance directly.

Weird, I haven’t been able to either. However I was able to subscribe to other Lenny communities. Maybe something is configured in that instance that won’t allow us to subscribe?
