Inaccessible communities? (EDIT: solved) - eviltoast

Hello, I’m new here! I’m currently trying to find communities to join. One of them I ran across which I’d personally like to join is https://lemmy.world/c/dfw , which I believe should translate to https://sh.itjust.works/c/dfw@lemmy.world , but that currently gives me a 404. Is there any reason for this? Am I doing something wrong? I appreciate the help!
