Hey! Thanks for looking into this. I posted this from lemmy.ml because I was able to subscribe from this instance. I was also trying to subscribe from https://lemmygrad.ml/c/croak@r1b.it and that’s where things are failing.
As a result, yes, I can see your new post from https://lemmy.ml/c/croak@r1b.it at https://lemmy.ml/post/54201793 but I cannot see it on lemmygrad!
I’ve had enough adventures with federation woes that I wasn’t in too much of a rush to get this sorted, though I’m looking forward to being able to see frog posts everywhere. I did also reach out to the admins on the other side, and will ping them in a day or two if they don’t run across it before then: https://lemmygrad.ml/post/13069086
