Thank you for your help, those instructions are very clear. I’ll try it out later today and hopefully that should do it!

Unfortunately, that does not appear to be working. When I first set up my Lemmy I was unable to see any federated communities. It was only after I put Lemmy.ml into the allow list that I was able to access Lemmy.ml communities and see posts by Lemmy.ml users. I even just tried deleting Lemmy.ml from my allow list and it went back to the previous behavior. Could I have some setting wrong?
