I believe this can happen if your instance (in this case lemm.ee) doesn’t yet know about the new community. But if you enter the full url (https://lemmy.blahaj.zone/c/lemmy_wishlist) into your instance’s search, it should look for it and find it. Maybe you have to wait for a couple seconds but for me this usually works.
I decided to make this over at https://lemmy.blahaj.zone/c/lemmy_wishlist
How do I subscribe to it? I try to type it like this
https://lemm.ee/c/lemmy_wishlist@lemmy.blahaj.zoneBut it throws me 404. Meanwhile,
https://lemm.ee/c/196@lemmy.blahaj.zoneworks fine.
