I believe it just means that the instance you tried to subscribe to hasn't responded to the federation request yet. Just wait a while and it'll resolve itself, assuming they haven't blocked you or something (and assuming that instance isn't down).
And if it doesn't work itself out in "a while", it's safe to click pending to unsub and then try to resub again. Though doing this a million times in a row while lemmy.ml is groaning under load is probably not helpful.
