can't access some communities in connect but can in web

I can’t access lemm.ee/c/imaginarymechas@lemmy.fmhy.ml in connect, but I can if I browse on the web. Am I doing something wrong?

Edit - lemmy.fmhy.ml is down and has been for >3 months. I’m guessing Connect knows that and can’t post there. It’s frustrating that the web version lets me post there without letting me know.
